What are some fun activities for cognitive development?

What are some fun sleepover and party activities?

• It's my 14th birthday party. People will come around 2-4ish (undecided). We will spend about an hour or so at my house, waiting for everyone to come and doing activities (help?)! Then we will load up a couple cars (I'm inviting 12-15 people, plus me) and go to the beach. We will do activities (help!). When the sun goes down, we will have a bonfire at the beach and make have dinner, make s'mores, and do any activities that are fun in the dark (help!). Around 11pm, we will load up the car and go back to my house. We will jacuzzi and watch movies and do activities (help!). Are there any fun activities that you know of? I am stumped!!! (note the help!!) I suppose after we get back and go in the jacuzzi we can do mani/pedis and do facials since we just came back from the rather dirty beach. This is all in late september or early october. Thanks.

• Answer:

  Well before you go to the beach you guys could each make a little snack before you go it gets really hungry(trust me) Individualized pizzas are great. At the beach is were the most fun will be. If they have a volleyball net you could do water volleyball. Play with a giant beach ball in the beach. Build sand castles. Gost in the grave yard in the dark is always fun. Or hide in seek in the dark.
