how close is each of the parks?
Disney Parks: AK is closest at approx 5-7 mins driving time. DHS & EPCOT are next approx 10 mins driving, MK is furthest and is approx 15 mins driving
Seaworld is 15-20mins
Universal 20-25 mins
how easy/convenient is it to get to the parks?
Easy, for WDW you can use sherbeth road or the main entrance off 192, but sherbeth feels quicker (and definitely is for AK). Allow time for parking and getting to the front entrance of the park, but we find it a breeze.
are the pools heated?
Community pools are heated in cooler weather. Private pools (if staying in a pool home) are usually by arrangement with the owner and for a fee)
are there restaurants and grocery stores closeby?
Yup. Approx 1 mile away (or less - haven't measured it!) is the Formosa Gardens Plaza with Outback, Giordanos, TGI Fridays, Red Lobster, Carrabbas, Cracker Barrel. Other restaurants nearby on the 192 (in both directions) include CiCi's Pizza, Key W Cools IHOP, and more. Rolling Oaks (new shopping area near 429/192 has Longhorn Steakhouse, Chillis, Flippers).
Groceries: nearest, but most expensive is at Formosa Gardens Plaza. Go towards the 429 (left on the 192) and you will find a Publix and across the street at Rolling Oaks a new Super Target (with food store and Starbucks!). A bit further down on the 27 just north of the 192 is a 24hr Super
Walmart (and yes, I have been there shopping at 2 am for groceries on the night we arrived!)
Love the location. The resort feels green and expansive. Clubhouse has activities on (they had face painting (free), bingo, karaoke and more when we were there) some things are free, some have a fee. There is a tiki hut bar at the clubhouse selling drinks and food.
