We are going on the August tour of the Galapagos. I am not a strong swimmer and was wondering if anyone knows if they have flotation vests for snorkelers on Isabella II. I would like to try snorkeling but am a little afraid without something to help with flotation. Has anyone gone in August, was the water rough? I was reading on another site (probably a smaller boat, too) that it was so rough they couldn’t eat dinner.
