We are 1st time RV travelers(suggestions on co to rent from). Going to Alaska in July 2011 for 10 days. We will fly into Anchorage and want to visit Kenai Peninsula and Denail. Suggestins on which to see first/good RV parks. We are thinking of ice hiking in Exit Glacier and Boat trip vs kayak trip in the north and hiking and bus (independent vs tour) at Denali. How long will our drives be in between locations?? Anything that is a must see.
