DO NOT LEAVE the tourist areas on foot! Stick to your hotel, the boardwalk, the beach. AC is an extremely dangerous city if you get away from those areas. Even driving can be dangerous. A hooker jumped right in my brother's car once when he was stopped at a light (keep your doors locked and your windows UP while driving anyplace in AC or Ventnor).
Will you have a car? If so, I'd heartily recommend day trips to:
Smithville--quaint little 'villiage' type place up Route 9--interesting shops, nice restaurants.
Brigantine--is a residential shore town (Just North of AC). Not a tourist trap, but the beaches are much quieter and pleasanter than AC. And if you go to the north end, you may just see some of the little endangered foxes that live there
Ocean City--just South of AC is a much more family-oriented place. You can safely roam pretty much any place there.
Lucy--if you're on Absecon Island, and have never seen Lucy, you really shouldn't miss her--larger-than life-sized elephant. Just head South on Atlantic Avenue, she's in Margate, right off the beach. Originally built as a hotel.
Brigantine Wildlife Refuge--not on Brigantine Island, but up Route Nine. Great day trip. You can see all sorts of interesting shore birds. There are observation towers here and there so you can get a better look.
Cape May Zoo--in Cape May Courthouse is supposed to be very nice (haven't been there myself, but I've never met anyone who went who didn't love it. Think it's free?)
There is an outlet shopping center in AC.
If you're from out of the area and haven't been to Philadelphia, it's only a little over an hour via the Expressway--loads of things there. Museums, America's First Zoo, all the historical buildings and sites, theater, the famous Italian Market.
There's Wheaten Villiage in Milleville, NJ with a glass museum, resident crafters you can watch, and the best part--the glass blowers (you can even make your own paperweight--but I think you have to reserve that ahead of time).
There are several wineries around that invite visitors in.
Sorry if I've been a bit of a downer about AC, but I live nearby, have a sister who lives on Absecon Island and I know just how bad that place is. I avoid the place at all costs. Only time I skirt through even a corner of the place is when I'm going to my sister's house and have no choice but to drive onto the island to get there. Again, do not leave the beaten track, and be very, very careful. I'd actually recommend taking a friend or someone with you, so you won't be roaming around by yourself while your husband is in his meetings. Parts of it are definitely that dangerous.
