I loved this tour. Acadia is a special place and the bus tour was outstanding.
First of all, the Acadia National Park is really beautiful and definitely always worth a visit.
But unfortunately we were not really happy with the travel agency. Our guide Jane didn't really seem to be very organized and the communication during the trip was quite bad. For example we skipped the stop at the Salem museum on the way back without even mentioning it.
What really annoyed us was the so-called optional stop at the buffet which costed 15. Jane told us that there would probably be no other restaurant to eat, so that we had no chance but spending the money and hoping for a decent buffet. Upon arrival we were unhappily surprised: the restaurant wasn't really clean, the food below average and we had to sit in a extra room which was really cold. Even more annoying was the fact that arriving at our hotel which was quite good we found out there would have been a restaurant right next to it!
Furthermore, be aware of the extra fees not included in this price: 62 in total 15 for the Acadia, 15 the buffet, 30 for the cruise and 2 for the Portland Lighthouse - weren't really sure if they even overcharged us on those things.
Jane was lucky to have John as the bus driver, as he was the only one who seemed experienced in this trip and was really nice.
Last but not least, the agency Sunshine Travel seems to target especially Chinese tourists, so don't be surprised to find yourself on a bus full of Chinese who speak exactly as less English as our english-speaking guide Jane.
