We had 8 day park hoppers this past June. We went to AK 2 days, MK 6, Epcot 3, Studios 4.
A side note-DH said that this was the best time he ever had at Epcot. We got there at park opening did a few things in FW and headed to WS at 11. We made a leisurely stroll around the WS and in spite it being very hot, read 98 degrees, we really enjoyed ourselves. Loved the Kim Possible adventure..... We left the park around 3 and came back another day to finish up FW. We came back one evening specifically for Illum...got in the park around 8:15, found a great spot near Germany and enjoyed Illum. It was a leisurely walk out of the park.
