Hi, Andrew, and welcome to planDisney! It sounds like, "Adventure is out there!" could be your motto.
Yes, you can walk around
Aerophile - The World Leader in Balloon Flight, although if you're afraid of heights like me, you may not want to. Hahahaha! There is a narrow walkway along the outer rim of the balloon, and you can move around it freely, which allows for stunning 360-degree views. On a clear day, visibility can extend up to 10 miles.
Once you've enjoyed your tethered balloon ride, why not make a day of it and also take a ride with
Vintage Amphicar Tours? Your Amphicar starts on land, then cruises into the lake for a boat ride that concludes back on land.
All that adventure is sure to work up an appetite, and you'll find plenty of options for dining at
Disney Springs. In the spirit of adventure, check out
Jock Lindsey's Hangar Bar, where you'll get the sense that Indiana Jones himself might saunter in at any minute to visit his ol' pal.
Andrew, I hope you have a great time seeking adventure and that you'll bring your other planning questions back to us here at planDisney.
Have a magical trip!
Melanie
