I went to Bass Pro Shops last year, and I think is was $38.00 for 4 of us. I tipped him well, on the return trip I called the driver directly, and He returned us for $20.00!
It might be cheaper to rent a car for a day and then you can go anywhere you want, including eating on I-drive or elsewhere. You can rent one on property at the disney car care center, National & Alamo are there.
