We are going to be there May 16 to May 23, staying off site, and planning to drive to the parks because the hotel shuttle does not leave until 8:30 each morning. I have tried to find out if we go from for example AK to the MK will we have to pay to park at each park, or do you just pay once. Also, how bad is the traffic at the end of the day? The only other time we were there we stayed at the DTD hotels and used their shuttle, which was excellent .
