L.,
We, too, used to take much more adventurous vacations. (Our last trip before kids was the Ecuadorian Amazon and the Galápagos Islands.) It is, however, a different kind of fun to vacation with kids and it won't be that long before we can take them on some bigger adventures. (Machu Picchu planned for summer 2009 - kids will be 6 and 4). Incidentally, my husband stayed home with our first for two years, too.
This is what we have done since they were born with pros and cons:
1. When my eldest was 9 months old we went to Abaco, Bahamas. Stayed at the Bahama Beach Club.
PROS: It is a relatively small island and you feel like you have the beach (rated one of the top in the world) to yourself. You can tool around in a golf cart to most places. It is VERY kid friendly. There is a spit near the resort that lets you walk out in ankle-knee deep water for about 200 yards. It is the safest beach for kids I've ever been to - despite the fact that there are no lifeguards. This place is REALLY quiet. We were there 10 days.
CONS: It is VERY expensive. The airfare is expensive. The food is ridiculously expensive. It is VERY quiet.
2. When eldest was 18 months old we went to Newport Beach, California. (Newport Beach Marriott)
PROS: It was close to EVERYTHING! We went into LA, drove to San Diego (San Diego Zoo and the Wild Animal Park), walked along the tide pools, shopped Laguna Beach, went to Disneyland, etc. There was a lot to do. We were there 14 days.
CONS: The Newport Beach area is the famous O.C. - quite a bit of it is high priced. Our condo was large and fully equipped, so we bought groceries and ate breakfast in the condo every day. There were no down sides, really. It was a great vacation.
3. For the past two years my parents have rented houses in the Estero/Bonita Springs area of Florida for March. The kids and I have stayed 3 weeks - my husband has joined us for 10 days.
PROS: The house has a pool in the lanai. For the kids, nothing else matters. We've been to several spring training Twins games. The beach is fun. The Instent (sic) Beach Tent has been indispensible. It is fun to rent a pontoon and tool around the Thousand Islands near Naples.
CONS: It's really too far to drive to Disney for just a day. We wouldn't have done this unless my parents were there.
We don't know what we're doing this year yet. I would like to take the train to Glacier National Park.
