Hi, absolutely trans is very expensive on the buses and they are notoriously not on schedule. Parking at Disney is really not a hassle. No one moves lots of people better than Disney. If you have kids or even if you don't, the tram ride from the parking lot to the park is always the "first great adventure" especially at Magic Kingdom!
Also remember parking is good for all day and night and at any Park. So you can hop in the car, head home for a mid afternoon nap or swim and head back at night and park.
We helped two friends who work with my spouse at Disney over the winter to rent a condo for 3 months at WPalms. We researched it with them, toured everywhere and it is very very nice. The pool complex is big and fun and the club house is full of stuff to do.
Getting to Disney is very easy. Turn left out of WP onto Formosa Gardens Blvd...take FG to Livingston ( a small but untraveled road about a mile north on Formosa Garden.) If you miss it don't worry just take FG all the way to 192 Take Livingson over to Old Lake Wilson and turn left. Take Old Lake Wilson to 192, turn right and go about 2 miles to big Disney entrance. There are other ways to get there but this is now about as fast as any.
To get home, have some fun and follow the signs to ANIMAL KINGDOM. There will be one or two quick right turns off the main highway in Disney so stay alert. As you approach Animal Kingdom stay LEFT TO ANIMAL KINGDOM LODGE. You will come to a stop light...turn left on SHERBERTH ROAD. Follow
Sherberth all the way to 192 and turn right...Formosa Gardens Blvd will be a left turn in about a mile...congrats, now you are a Disney expert driver!!!
Enjoy...Ted
