5 year old boys birthday party ideas.?

I would do the food right away and the cake soon after. Just make sure you have some chips or other 'cheap' snacks in case the kids all get hungry later. Running on the beach and playing in the water can make them hungry again and if they food is early they may want a snack later.

I would get some soda. I agree the kids should drink juice or water, but the adults may prefer soda. Good 'beach' party favors would be water guns for everyone or go to the dollar store and buy a shovel, bucket, sand castle set for each, they are only $1 or $2.

Or you could get the little ones they sand toys and get the older kids a cheap boogy board, the dollar store has them as well. What I would probably do is take a bunch of beach toys for the kids to play with: stuff to dig holes and build sand castles, a couple boogy boards, a football, volley ball, soccer ball and frisbee. That should cover all age groups including any adults who want to play, because we all know men are just really big kids.

Then give them each a little loot bag full of summer goodies: squirt gun, water balloons, bouncy balls, whistles, etc.

Okay, as for food you're going to want to have something easy and simple and not very messy id suggest getting 2 or 3 buckets of chicken wings with rolls. As for drinks you're right on key. And yes you can keep the cake in there but you're going to want to put it in a separate ice chest.

Party favors: You should just go to the dollar store and get the girls little princess crowns and lip gloss and the boys some water guns and the balls that soak up water and through at people.
