thank you both for your input!!!! I'm going down around October 15th for 6 nights. So far, I booked a Preferred site as the Premium sites were not available; however, they said I can keep checking back for anyone who may cancel.
I guess the only Preferred (Pet Loop) is the 300 ... My unit is 31 feet long and with the slide out is about 12.5 feet wide. I wanted some space on the side for chairs, table, awning... Also, I will have a rental car, so I guess I will have to pull the unit back on 1/2 the pad and 1/2 the sand area??? Will this make it unlevel???
