I can only give you information on EIR.
I am sure both are wonderful resorts. They have the same builder so I am sure they are very similar.

Grocery Stores
At the Junction of the 192 and Funnie Steed Road is a Winn Dixie
http://formosagardensvillage.com/
If you turn left on the 192 and drive for approx 1 or so miles to Orange Lakes you will find a Publix Supermarket (on the right hand side).
If you continue left on the 192, take the 27 north (right tuen), just after you get onto the 27 there is a 24 hour
Walmart with groceries. Turn right at the first set of stop lights to access it. The walmart is set off the road with smaller stores/restaurants in front of it so it may not be instantly noticeable.
