Tripadvisor has neat tool worth checking out on their vacation homes page: A Hotel Vs Vacation Home cost comparison calculator.
Simply type in the destination for your trip:

And find out how much you will save, based on your destination, # adults, # children, # nights and how much you eat out:

It would be nice if they would make this available as a “widget.”







Nice tool. Although it’s only a rough guide, it’s a good indicator of potential savings.
It seems Tripadvisor is concentrating on the Vacation rentals market, what with Flipkey and all. The competion for Homeaway will be good for owners.
Boavista: Yes, it should be good competition. I am excited to see how much the market expands when Expedia and Orbitz get into it as well.
