Bar Harbor Private Tour in October

There are four of us sailing to Bar Harbor on the Celebrity Summit Oct 13. The bus won't be running that far into Oct and Olli's trolley doesn't seem to meet our needs. We found a private tour operator but he already has a booking for two in his minivan. I don't really want to cram three adults across in the two backseats of his van for the rest of us.

Can anyone recommend any other tour operators?

Thanks!

Well that was fast! Got a call from the guy with the already booked tour. One of the other drivers in his guild is going to take us around. We'll let you know how it goes.
