We will be at a resort at Xpu Ha beach and would like to go to the Jungle spa. We are not too adventurous and a bit physically limited (so treking all over like we did in our 20s is not an option). How difficult is it to take the colectivo up there? Or, is it better to take a taxi? How expensive would a taxi be to/from? What else do you suggest we do for the one-day trip up to Puerto Morelos? Any suggestions or assistance would be great
