A few ideas, while Mrs. BD and I plan our trip to visit the Pupette in Prague this Spring (think we'll use Club ABC to save $ this time. Prague is a hot place these days for the youths.):
VRBO - Vacation Rentals by Owner. It's worldwide. I like to move around on my trips, but it's a cool idea to rent a place, rent a couple of cars, and bring the whole family and your best friends for a week or ten days. When my Dad was slightly younger, he used to do this for the whole family in Tuscany. Kids, their spouses, grandkids, etc. Two weeks, villa with pool and a cook and a ton of bedrooms, spare cars, walk to the village. Nice. What's the point of a little money if you can't enjoy it and share treats with your family? Uncle Sam will take half your money when you croak to buy votes.
Vacations To Go: Discount ship tix. You have to pick a nice ship, however - not one of the tacky mass-market ones which are beneath the dignity of Maggie's readers. The Silver Explorer is a nice one, with only 132 passengers. Here are some pics of her. I am in favor of the cheaper rooms on ships, because you are hardly never in your room anyway. On ships, I like to spend my time up on the deck. My friends at the Holland America line let me hang out on the bridge.
