ok,let's see if i make this clear enough for you
whichever you are staying at - the Amerisuites or Country Inn - once out of the driveway, bear right and follow it around to the end of the road. Take a right onto the access road which goes alongside the Osceola Parkway to the end - (set of lights there). At the lights go left on 535, stay in the right lane. At the lights for International Drive, bear right and follow the signs ( you will see a 7/11 store on one corner, Buena VistaSuites on the other side) Follow International Drive carefully, it will bear to the left a ways up the road. The directions are truly easy to follow
Reverse your directions from Sea World to the hotels - right on International Drive - follow it til I Drive bears to the right - get in left lane at the lights for I Drive and 535 (7/11 store and Buena Vista Suites) left onto 535 - stay in the right lane and 2 miles up the road right after going under highway, bear right on Calpso Cay Drive.
