Probably on dodgy ground here - as an owner of what I'm about to promote - but as we're pretty full then and I think it's right for you I don't care!

Look at the lodging section of this web site and have a look at the homes section. I would imagine for your family you will pay a lot less for one of these homes, than two or three rooms in a hotel and of the twenty or so listed there are plenty within walking distance of town. There are four right near us in Boca del Rio for a start.
