17th In 1 Month, Need Ideas

My birthday is in on month (12th Feb) and I will be 17.

I live in the UK, so a lot of ideas I`ve seen on here wouldn`t work (Beach parties, yard parties) because it will be winter.

We also dont have much space in our house, so space will be a problem.

Any ideas?

I was thinking of having a really childish party with pass the parcel, and other kids games, just for fun, but I`m not sure.
