Hey Hilary!
Welcome back to the Disney Parks Mom Panel! You are going to love the
Hoop-Dee-Doo Revue. It's a rip roaring good time.
While the way you proposed getting to the Hoop-Dee-Doo Revue from
Disney's Beach Club Resort will definitely work, I don't think this would be the quickest way to get there. This is partly because the walk from the Beach Club to the Monorail would take at least 15 minutes.
I would suggest using Disney Bus Transportation instead. You could take the first bus which comes to the Beach Club going to ANY of the theme parks. Once you get to that theme park you would take the first bus going to the
Campsites at Disney's Fort Wilderness Resort. If by chance the first bus which comes to the Beach Club is going to the Magic Kingdom, you would take one of the Fort Wilderness boat launches.
You are absolutely correct to plan for an hour and a half travel time. Even if you get there a little early there is plenty to do as you wait such as strolling through the stables at the
Tri-Circle-D Ranch.
I hope this helps your Disney planning. If you have any other questions please come back and see me.
Wishing you a magical vacation and a pixie-dusted day!
