Birthday parties in Kent?

[SomeCommonThing]

I know, Christmas is barely done, but it's DS 10th birthday soon and he's decided he wants a party.
His friends have had laser tag, trampolining, and gaming bus birthdays so he's thinking something amazing.
I'm thinking something that is not going to cost me £200+ for 10 kids considering there is only one pay day between now and his birthday.

DS isn't into bowling, it's Winter so ideally something indoors, he's really into gaming and stuff. And we don't really want to repeat someone else's recent party.
Our house is also definitely not big enough to host a party here.

Pressed send too soon 🙄

Do any of you have an ideas or suggestions of birthday parties in Kent/Medway that you have done that were good and not too expensive?

Thanks

No idea of the costs but Ninja Warriors in Chatham? It wasn't a party, the mum bought just entry tickets and paid for drinks. Low key. We went back to their place for pizza.

I didn't know that was there, thank you I'll have a look!
