Sebago snorkeling tour was very good. There were 6 people in our prty (2 adults, 3 children and 1 toddler). Stroller was allowed on it. My kids enjoyed the catamaran while sailing and sight seeing. They provided clean snorkeling gear and fins and post snorkeling, they provided soft drinks and beer for everyone. You really should bring snacks since they only had $2 chips and $ cocktails on board for purchase. While snorkeling on the site where they brought us, the ocean water wasn’t as clear as I though they’d be (reminding me I’m not in Cancun) , although I did see some fishes, and I spotted 2 sting rays which was cool! Overall, I do recommend this tour, the staff were friendly and approachable and most of all helpful. We enjoyed it, we’ll be using them again.
