We recently purchased our 42' Grand design reflection 5th wheel. Have taken her out 7 or 8 times so far with no problems. First trip to the fort will be July 4th week in a premium site. 2nd trip will be 1st week in December. Only thing available in Dec was preferred. is it possible? should i cancel? im checking disney site everyday, but have yet to see a premium become available. Very nervous about backing her in in general, but scared to death of a prefered.
