Don't know if GF has Krispy Kremes, but the donuts are best when they are FRESH.
There IS a Krispy Kreme down on I-192 - if you get onto I-192 around the MK area, you need to go to the left (towards Kissemmee). It will be on your Right, down a little ways.
If you get onto I-192 by coming from DownTown Disney (get onto Hotel Blvd, and take a Right at the Crossroads); this road will take you down to Albertsons Grocery store, and basically ends at I-192. Turn Right, and Krispy Kreme is on your left, down a little ways.
It's across the street from Long Horn Steak house (a GREAT place for FABULOUS steak).
Try to get the donuts from the actual store - they are so much fresher, and are WONDERFUL when they are still warm out of the oven. It's also really cool to see the big machine that makes them - you can watch them make the donuts while you wait or eat your donuts.
Have fun!!!
