We are planning our second trip to Disney this May! We stayed Polynesian last time but it's priced way too high for us this time. We are considering POP, POR or Coronado. All are priced about the same. We have 2 girls, ages 3 and almost 6. What resort do you think would be the best fit? Our biggest concern is transportation. We were spoiled by the monorail last time. We will be spending the most time at MK and Epcot. Thanks!!!
