Birthday afternoon suggestions

[inappropriateraspberry]

It's my birthday on Saturday. I'm busy in the morning and not expecting to do anything special, not a big birthday! We'll be having a takeaway in the evening and some fizz, but DH has asked me what I want to do int he afternoon and I'm stumped!
Will have the children with us, but not sure what I want to do! I don't want a Christmas market (too early), don't want to go shopping and have no other ideas!
We're rural, so driving too far just isn't worth it for a few hours. Only thing I can think of is a walk somewhere, expending in weather. I'll be free from 1pm, so only 4/5 hour window and don't want to be rushing around. I would love some suggestions!

Happy Birthday!
What age are your kids? Do they absolutely have to be with you?
You could have a family day at home?-all put your pjs on and play games/watch films, if that would be a change for you.
How rural are you?- can you not ho into town for the afternoon?- go for lunch/afternoon tea/birthday cake/ice cream or something?
There's always the cinema if you like that.

Or... ditch the family for the afternoon.. husband can have the kids- you head out with a mate or do something just for you for those couple hours (spa or hairdresser maybe,) then have your birthday takeaway/cake/whatever with them in the evening?

Cinema is a good idea, but I just looked and there's nothing I want to watch!
We have lots of family days anyway, the children are primary age.
Local town is small, nowhere to go for an afternoon tea (or not that I'd choose!). The problem is, I know I can do a better job at home most of the time and begrudge paying someone else for food I can do better! Maybe I'm just fussy, but I wouldn't enjoy it.
It's either whole family or something on my own - no one to babysit this weekend.
Not really one for spa etc. I think I'm just awkward! I'd like to wander around somewhere but the kids will get bored and it's no fun on your own!
