Assateague Island National Seashore

My friend has been bugging me for the last few summers to take a BC camping trip with him on Assateague. Just an overnight out-and-back.

I'm not too thrilled with the idea, with the heat, sand, bugs, and having to carry all the water.

What do I need to worry about? read: any ideas to lessen the impact of the aforementioned issues, to make the trip somewhat enjoyable?

Thanks.
