rice_burners_suck asks: "For some reason beyond my comprehension, a whole bunch of family members are coming in to visit over the next month. The busiest weekend will take place when I'll have six guests to entertain, and I don't know where I'll take them or stay with them. I'd like to have a good time without breaking the piggy bank. Where, on the Internet, can I find good vacation places and compute a budget? I'm thinking of a service similar to AAA, but online. If something like this doesn't exist, how could I go about implementing one myself?"
