HELP ME CHOOSE PLEASE!

May is coming, and in early May, I normally start planning my b-day party. I have a few ideas, but I'm not sure. Right now, I'm leaning towards "Animal Safari" theme. Please read this before you vote.
Party pros and cons:
Animal safari, Pros: I love animals, and I already have some ideas for games, and decorations. Cons: Can't think of any.
Luau, Pros: I could have it outside, and my mom said I could get sand, and put it around the plastic kitty-pool we have. Cons: I can't think of any games to play, and my friend already had a luau b-day party.
No theme party, Pros: I could do any game I wanted, and decorations could litteraly, just be my doodles. Cons: it's always fun to have a nice themed party.
Slumber party, pros: who doesn't love a slumber pary? Cons, I had a slumber party last year, and I can only invite 2 people.

I vote animal safari theme

Thanks for voting!
