Ollie's Trolley vs Acadia National Park tours?

[snoopy5386]

Ollie's Trolley vs Acadia National Park tours? We are visiting Bar Harbor in July and want to take one of these tours. Is there an advantage to one vs the other? Does either vehicle offer A/C or better views? Preferable to be on a trolley vs a school bus?

They both take the same route on the loupe through the park, and sitting on the left side (on the same side as the driver) offers better views.  We used Ollie's Trolley and were very pleased, but you will find that folks who use Acadia National Part Tours are also pleased.
