9 year old children’s party

Also, the best parties that dd has been to this year were a disco/sleepover at a friend's house and then another who hired a small swimming pool just for them so they did an hour of swimming and then went to Wetherspoon's for dinner!

Unless you're rolling in it, anything 'amazing' is going to be really expensive. Climbing was £18 per child, not including any food. So for 10 of them, was about £250.

🤣

At that age, parties get smaller and more personal, not big whole class parties. For dd's 9th birthday, we did a 'spa day' at home with about 5 friends: pizza and cake, they each got nail varnish and hand cream and face masks in a little bag, then they painted each others nails, laid around on the floor with their masks on for 10 minutes, did some dancing and I put on a film. For her 10th, we went to a climbing centre and did an hour of clip n climb and then had pizza and cake in the cafe.

Budget?
Your local stables might be able to do horse riding in groups with lead reins?

I would ask what she wants to do. Throw out some suggestions if she's stuck for ideas. Then let her know how many people she can pick based on the party/activity.
If you want to go really big and blow some cash, I would be thinking about taking DD and 3 friends to a theme park for the day, but that level of spending isn't necessary IMO.

I agree with others that a chosen activity with a smaller group is both the norm and the preference for 9yos. DD had a sleepover with 3 friends for her 9th birthday, and went to the cinema then out to dinner with 5 friends for her 8th. The dinner in particular made them all feel very grown up (get them their own table with you on a separate but adjacent one). She has attended trampolining, climbing, indoor mini golf, and Ninja Warrior parties over the last year which each had 6-10 attendees.
On my DCs party wish list for future parties is tobogganing/snowboarding lesson, Go Ape, and indoor skydiving (not that they'll necessarily have these, it's just what they've spotted and would like to do!). Hall parties stopped at 5yo IME.

Roller disco?

Silent disco

Swimming party, especially if you can book an inflatable session with the pool.

High ropes/go ape. Look for local council owned high ropes, often far cheaper than Go Ape. However, could be very pricey with 20+ kids

Clip n climb is great for kids too.

Find a pump track and see if they have BMX parties or whatever?

Ds1's class did whole class yR fading to all the boys/ girls through y1/ 2 and fading to friendship clusters for more expensive activity parties by y3. Covid happened y4. DS2's class were following a similar pattern when they got cut off in y2.

Few 9yos would want the whole class at a party, and would make it clear if they did. They want their friendship group.

What about a swimming party?

This sounds kind of wrong. More like you want to impress other people.

I think you should ask your DD.

I feel like the only way a whole class party would work for that age group would be to have a disco (lots of companies do glow in the dark etc) which would be quite fun.

If you aren’t set on a whole class thing (rare post year 2 IME) then the parties my children have most enjoyed at that sort of age have been:

go ape
pizza party
trampolining
clay/art making party
paddle boarding
chocolate fondue and dancing at home

you could always ask her who her ten best friends are or if she had a hypothetical party who would she invite etc.

I think she'd rather have a sleepover with a few friends than a whole school party. Or take her and a couple of friends out for the day.
If you really want a big party then I'd wouldn't have an entertainer. Music, food and maybe some craft activities or similar.
Honestly, I'd ask her what she wants to do.

What your daughter like to do. My DD aged 6 and love that party but aged 9 I suspect she like a smaller thing with a few special friends.

Dd is 9 this month. we are having 12 friends to an outdoor animal park place that does parties.
Tbf its all i could get at the last minute as left it too late. It dint cost ant more for 12 instead of 8 which is the amount of invitees dd originally asked for.

Last year we did cinema and year before a small themed party in the garden.

Havent had all class parties ince year 1. Covid happened ao not exactly sure when they would have naturally ended but its now definitely smaller gatherings.

As others have said it sounds like you want the party for other children not your DD.

You need to ask her what she wants, at 9 my DD had had enough of big parties and wanted to do something with her best friends so we did Clip+climb & trampoline warehouse combo then had nandos.

The year before we had a swimming pool party, the one before that a trampoline warehouse and then before that it was soft play parties all for the class. Other options for events in your area might be sledging on a dry slope, horse ride, Go Ape, Go karting.

Disco, mocktails and pizza. Get a DJ

Dd was 9 this year and the favourite parties have been at ninja places, trampoline parks or go ape.
Sleepovers are also popular though you couldn’t have the whole class unless you’re insane.

When you say surprise do you mean secret invites because clearly you can't expect 45 kids not to mention it to her. If the activity/ entertainment is the surprise you might get disappointed children or kids not coming because they don't know if they'll enjoy it.

I don't know how many the science party people can cater for but that would be something different? I'm surprised she'd want to have the whole year there.

DD turned 9 in May and specifically didn't want a full class party this year, they've all started breaking off into smaller groups in yr4, whereas previously everyone was friends with everyone. DD wanted to take a couple of friends adventure golfing and for lunch in a restaurant. They had a lovely time then I took them all back to our house for a few more hours of playing, chatting and eating junk.

Ask DD what she wants to do.

Why does it need to be a surprise? She knows when her birthday is!
