Any opinion on which of the Utah parks are the most "must see"? My wife and I have been to Rocky Mountain and will probably skip it this trip. As to the LA area, work requirements (a 4 day conference) make that unavoidable. We'll probably take a day at Disneyland (kids interest not mine:) and would also like to get to the beach for a day. Any RV parks or campgrounds you would recommend that have easy (walking preferred) access to the beach?

Thanks!
