Ok so my birthday party is in 20 days but my birthday is in 18 days(b-day may 13,b-day party may 15).

Q#1-Should I separate the people who like each other or keep everyone together to get to know one another

Q#2-Should we eat before we go swimming or after

Q#3-What games can we play

Q#4-What should we put in the scavenger hunt and prize auction


Any other ideas would be great

Thanks Kaitlin
