Hi! I am thinking about a trip to WDW in early December and would like to be armed with lots of info before talking to the rest of my family...So here is our situation: I have a DS who is 4. My parents are on the older side (Dad will be 80 by the time we go!). He doesn't use an ECV at home (doesn't need one) but with all the walking at WDW will definitely rent one in the parks. I'm not sure if my sister (who is single) would join us , but it's a possibility. I want to stay at the Poly because of the convenience and because it looks really cool. Two things: what would be the best room option for us? Two rooms seems really expensive...But not sure what else to do. Also, what longhouse should I request? Mobility isn't a huge issue, I would just want to make it easier for my dad to get around and enjoy himself. Proximity to a pool would be nice for my DS, but not essential. Any help is much appreciated. Thanks!
