My B-day is on Febuary 2nd we are having a dinner for me but I don`t want a dinner. Any ideas?!

Anyways we are having a dinner for me on a Sunday night and I`m turning 12 and I want it to be fun so I was thinking about throwing a party but my mom told me last year that i could have a party and now she says I`m having a dinner any ideas for what to do to through a party and any ideas on how to tell me mom that I`m want a big party without hurting her feelings? Most of the kids have them on a friday night so I want my party to be good even though it`s on a Sunday night. I`m sure a few of my really good friends will be spending the night I just really need some good idea!!! If you know of any websites let me know! :D
