So many hotels sleep 4 or 5. Where is the best place to stay for 4 small children with a free breakfast buffet? Holiday inn family suites is sold out when we want to go in February.
You would need your own car (or hirecar) but renting a private house could be an option to you. Granted it won't have a free breakfast, but the savings in room rates is likely to allow you have breakfast in one of the many cheaper restaurants along the 192. Alternatively you'd have access to a full kitchen so you could save even more money by having cereal,toast,bagels etc for breakfast at "home".
With 4 kids it's an accommodation choice I'd seriously consider, you can check out some of the options on http://www.vrbo.com if you'd rather use a management company I had a good longterm relationship with http://www.pr-vacation.com
