To assist those needing accommodations here are some helpful internet instructions. First, go to GoogleMaps:
http://maps.google.com/maps
Right next to the big Google it says Search the Map and then Find Businesses. Click Find Businesses. Then enter RV Park or Hotel or what-have-you for the "What" and (for this search) Winter Garden for the "Where". This way you can also have the map to find it handy.
I think these two are the most promising:
Orlando Winter Garden RV - more info »
13905 W Colonial Dr, Winter Garden, FL
(407) 656-1415
Suncoast RV Winter Garden - more info »
12201 W Colonial Dr, Winter Garden, FL
(407) 654-9437
Now parking the RV's near the Dog Park is possible, but could be challenging if more than 2 try to come at the same time. Maybe we can make arrangements to pick up the folks at the RV park. I have room for 2 or 3 people since the dogs are small and you can hold their crates on laps (for such a short ride).
