So maybe you can find an Xcalak forum for your questions?
edit: a simple search turned this up...
Can you get there by bus or cab?
You can get there by bus although it can be complicated. When you get to Cancun, you'll have to head downtown to the bus station by either cab or shuttle. When you get there, catch one of the ADO buses to Felipe Carrillo Puerto. Disembark there and catch one of the regular buses to Limones. Disembark and catch the bus to Xcalak.
The above scenario is really an over-simplification of what's involved. The arrival of your airplane has a bearing and so does when you get to Limones. If you don't arrive in Limones by mid-afternoon, you'll miss the Chetumal to Xcalak bus that stops there.
I've heard that you could hire a cab in downtown Cancun for about U.S.$125.00 to take you to Xcalak - I've never done it. A cab might also be substituted for a bus on one of the other legs of the trip. Bus to either Felipe Carrillo Puerto or Limones and hire a cab from there.
Buses leave Xcalak every day at 5:00AM and 2:00PM. They stop in Limones and then head south to Chetumal. If you are heading north, you'd get off in Limones and catch the next one heading north.
