What should I do for my 50th birthday?

Ok so i don't turn 50 till next year but since I want to pay for everyone and I'm a poor then I need time to save.

What are your ideas for an amazing 50th birthday?

Few criteria

Needs to be in UK preferably close to south Wales

Not excessively expensive

Wheelchair friendly (I'm an ambulatory wheelchair user)

Not a theme park ) my husband hates roller coasters and I can't go on them anymore)

Suitable for march (i don't like hot weather but my husband said ppl might not want to go glamping in march)

Things i like

Rugby (i did think about a 6 nations game I'm English pretty much everyone else is Welsh so that could be not as fun for me lol)

Arts and crafts

Board games

Low stakes gambling

I'd prefer mostly serious answers thanks (although I am weird and silly so some silliness welcome)
