I hate our holiday and want to go home

How old are your kids?
Can you not just stay at home. MIL and SIL probably don't like you either.
Say you've got the malaise. You'll have to just grit your teeth this time. But have a pretend stroke or something next time! If he wants to see his Mam with the kids let him get on with it. Have 13 days down time💄

Drive / train somewhere and actually do things then. You’re wasting it by sitting on your arse and ranting on here. Plenty of things to do so next time plan days out whilst you’re over here. It’s Easter so schools are out. You will have plenty of options open to you so plan next time.

Absolutely spot on!

Personally I think you are lacking somewhat in imagination! Others have suggested renting a holiday home which seems ideal. Why are you depending on your SIL's car? Why not hire your own and be independent?
Why not pay for your MIL to visit you? I know she is scared of flying, but so are loads of people, but they get over it if they want to see their family. Surely SIL could escort your MIL to the airport and you would be there at the other end.
It seems to me that you are simply playing the martyr. You chose a new life which is amazing, but for goodness sake, make the most of the opportunities that come with that choice.

Surely adults can make their own entertainment/fun/best of it?

Stop wingeing and get out and find what you like to do.

I’ve already posted that a train from Aldershot to London costs at BEST £11 for an adult (if you have a railcard) or AT WORST £22 for an adult if you don’t have a railcard!

Considering the OP can afford a $4000 trip to the ‘shitty’ UK, those prices are fucking awesome!

Get on a train to some fabulous places and stop moaning! You’ll be home soon.

Get the train up to Scotland 🏴󠁧󠁢󠁳󠁣󠁴󠁿 our water is so much nicer

Exactly how I feel being dragged to the in-laws in France every year. I've now started refusing to go. My husband's family, he can take them there.

Says in the op mil scared of flying. They need to just catch up via zoom it all sounds painful for everyone involved particularly poor sil who deserves a medal.

I really can’t imagine wanting to teach my children to kill animals for the fun of it. And to think it’s an important skill and a fun family activity. What sort of parents would do that..

Would it be cheaper to fly her out to visit you? Then you could still do some work.

Surely you can't expect to slag our country off & get positive feedback! Stop whingeing & get off your arse & do something! We have some beautiful walks in Surrey. Get off your high horse then go back to the USA where everyone is fat and over eats & gets shot at then! 😂

I’m not one of those people who defends the UK to the hilt, it definitely has its fair share of problems. But at least we don’t have to worry about our children being shot every time they go to school. I can put up with slightly worse scenery just for that, to be honest.

OP just wants something to complain about and try to make out that her life in USA is sooo much better. They’re too tight to hire a car, so that they can go further a field. There’s lots of lovely places to visit in the U.K. I stopped going abroad years ago. It’s the Easter holiday so they don’t have to get back every day for SIL’s kids. And let’s be honest America isn’t all that !

Maybe next time plan better. Tell the family you want to get out and do a few things. Plan in advance. I'd be bored anywhere if I just sat indoors for 2 weeks or wandered up and down a high street (which don't really exist in the UK anymore I might add)
There are plenty of things to do and nice places to visit - but they don't come to you - you have to go to them! A holiday anywhere is what YOU make it.

Yeah I finally clicked to that, bit slow today

Although one has to be careful walking across fields, have you seen how many people get killed by cows in this country, quite shocked me

Goodness!
I have a holiday barn and often rent to people meeting up. Its neutral ground, I think it might be a better idea next time. Bdetter still pay for your MIL to travel to you or meet you somewhere so yoy all get a vacation?

I would plan things on the way to see the family and maybe on the way back or days out and see her for a week maybe.

To be honest you are being ridiculous, you would be better organising a holiday in Europe where MIL can come to you and at least that way you would have a nice break. Or alternatively arrange to visit the Peak District or Devon or something with MIL, that would be a better break. If you turn upto someone’s home you will inevitable just become part of their day to day monotony. You need to have things planned.

She wants to c her grand kids and I think u sound very selfish. Not everyone has the same & the fact u described yr SIL in that manner for me that’s a disgrace. They re yr husband’s family that is what made him who he is whether u live in a nicer environment with or not. U can buy yrMIL a ticket it will be cheaper or when u visit rent a home from home for yrself and visit MIL regularly. There re so many ways to accommodate them without looking or sounding snobbish. I would never go on a public forum and talk about my family or husband’s family in that way it just sounds wrong to me. I just hope yr children are not picking up on this otherwise what exactly are they learning

I think the poster meant you can walk in UK woodland without getting eaten...

Central London is only 1 hour and 20 minutes away, go for a walk in any market, there are so many things to do in London, you still have the time to book a matinee show and go back on the last train after a nice meal.

Let’s be perfectly honest visiting family is shite at the best of times but three weeks of it when it’s doing nothing but piss down; your miles from home & your accommodation is pretty crappy too your not going to have the best of times, maybe make these holidays bi-annually & for two weeks instead of three; children are growing & all that xx

Then go then!
