Toad or No Toad ?- Grand Canyon road trip in a 23' class A

Grand canyon, no need for a toad. Use the bus to get around. we stayed in Williams but used a toad to get to the canyon. the train is OK but expensive and you don't get enough time to explore.
Yellowstone you need a toad. July is peak time. It is crammed!! There is very little parking at the attractions, sometimes waiting 15-20 mins for a car space. No space for Class C's or above. Plus 1 bison on the road holds up traffic for MILES!! We did Alaska !6K on the Class A 6K on the Toad. Best trip ever.
