WOW, sounds like fun...
First of all, Westgate Lakes is in a GREAT location to get to Disney. We drive right by there all winter to take short cut to the parks...when you exit Westgate on the east end there is a small roundabout circle...go all the way around and head north on Entry Point Blvd for about 1/2 mile toward highway 192. When you get to 192 go STRAIGHT ACROSS and you will be on Sherberth Road...Follow Sherberth for a long straight drive...look to your right and you will see the new Everest Roller Coaster in AK. Look straight ahead and find the big tree top that is a off color green...that is the Tree of Life in AK...then take a couple of turns and stop at a stop light.
You are now in Disney World!!
To your right is Osceola Parkway...Left is Animal Kingdom LODGE with the best buffet at Disney, Boma's, that I recommend highly!
Turn right and follow the signs...first turn left is Animal Kingdom and a mile or so will be left turn to all other Disney Parks. Now just follow the signs!
To exit Disney and get home, follow the signs in the parks to Animal Kingdom...there are some tight little turns to get there from the main roads in Disney, so watch carefully. Then at the last sign stay LEFT to go to ANIMAL KINGDOM LODGE, not Animal Kingdom. You will be back at the stop light, turn left go back across 192 and you are home at Westgate...
There is so much to do at Disney that advice is cheap...explore the boards and look at questions others are asking and it should help...
all the best...Ted
