Is a lifejacket recommended for snorkeling?
We are a group of 3 friends who are visiting catalina in a couple of weeks. It's our first time snorkeling and we are kinda doubtful about the level of swimming required for it. We are planning to take a guided tour where they said that they will provide us with wetsuits. 2 of us know how to swim (but not regular swimmers so not a lot of stamina) and 1 person knows the bare minimum of swimming (almost nothing).
My concern is that it will be tiring to swim+snorkel for the 1 hour of the tour that we are in the water for since there will be waves from the ocean as well. The tour company said that they don't provide life jackets but I think we can rent them from some other shop. Would that be recommended since it might make staying afloat easier?
Any recommendations highly appreciated!
