Other useful info
Isla de mujeres Is an 18min boat ride from Cancun. Although it's touristy, it is well worth a visit. There used to be a cheaper ferry only for cars, but they don't take pedestrians anymore, so Ultramar Is the only option. Tourist price is 150pesos one way (it's a black ticket), but if you kindly ask an islander to buy the ticket for you the price would be 42pesos (orange colour ticket), or a Quintana Roo resident (purple colour ticket) it would be 78pesos. Hitchhiking within the island is very easy, make sure to visit the Southern point as well.
