beach gift basket?

my mom is taking us to florida for winter vacation (our first time in florida) in february and i'm the only one who knows...she's telling my 3 brothers at christmas ages 7,12,15...i'm 16...we wanted to get them gifts that would coordinate with that...but we don't know what or how to give it to them...scavenger hunt, gift basket, each separately wrapped,??? and who should we give what to so that we can equally give out presents???? if there's a website or any ideas you have would be great

Wrap each separately. It's always fun to spend Christmas morning unwrapping gifts :-) Plus, I think 15 is too old for a gift scavenger hunt. For the gifts, I suggest sunglasses, swim suits, flip flops, and a beach towel. Maybe a disposable camera if they don't have a regular camera. The first items might be hard to find this time of year, so you might be best looking online.
