We will be at DW for the 1st time this April, and we would like to try dining at some of the different hotels. Is it time-consuming or difficult to leave the Magic Kingdom and go to the Kona Cafe or Whispering Canyon Cafe for dinner and then return for evening parades and fireworks? Or leaving Epcot to eat at the Cape May Cafe of Flying Fish Cafe and then return? We'll have a rental car, so I'm assuming that we would leave it at the park and take Disney transportation. Any suggestions?
