If it is a rustic place it has basic services we cannot ask for more there are two canvases, the blue one and the red one, I recommend traveling in the red one, they have better boats, bar service and sandwiches and their seats are cushioned, those of the other are made of fiberglass, they leave each half an hour and they go one and a round so you can choose who you want with
The sandbanks are a beauty. Punta mosquito with an infinite beach and a super pleasant climate became one of my favorites. The recommendation if you do not have a lot of budget is to bring a cooler with a snack and an umbrella for what there is not even a tree to shelter you.
To travel by ferry with the same company, just buy your one-way ticket with the one you like, since there are two boats, the blue and the red one, the red one is recommended and to return buy your ticket in Holbox, since if you want to buy them together ( round trip) you would have to travel one way in the blue and back in the red or vice versa.
