Oh dear... yeah you will be bored with AC after a couple days. But fear not, you can travel to other beaches and other cool spots on the shore and be amazed at all that is to offer. Look for "guides to jersey shore" and stuff like that to get a good overview of what beach area offers what. There is super-cool wilderness stuff down there too, the bay, Cape May and Wildwood are about 35 miles south. Drive down route 9 and look at the cool old scenery. Take a morning to go walking in the pine barrens - I'm not sure what state park is close to AC but look for Batsto or... well poke around. Maybe explore each morning, then get back to hotel, grab a towel and your beach chair and sit outside with a beer.
