We are visiting WDW from October 18-29, 2013. It will be myself, DH, DD age 7 and DD age 5. Out of Caribbean Beach (preferred room), Coronado Springs, and POP (preferred room), which would you chose? Please give your reasons and also any other helpful advice. Would you recommend having a rental car for any of these resorts? It is my first visit since the 80's and first time for DH and DDs. We are so excited! Thanks!
