I haven't been to this one, but I would suggest contacting the hotel directly. Even then, they might not be completely correct. Be sure to tell them which airport you're coming from.

I am quite certain that some of the directions on the spg.com webpage are slightly incorrect since the directions from Cancun tell you to take a left for the final turn whereas the directions from Merida also tell you to take a left while coming from the opposite direction. (The Merida directions are correct, I believe. I think that the Hacienda is on the north side of the road. Perhaps WChiCC can confirm.)

Take printouts of ALL directions with you. Search for the following coordinates in Google Earth. I am almost certain that this is the location of the Hacienda San Jose
21.0103613007, -89.292255088

This map should help you, but it is not as detailed as you might like. In fact, I think that it may even be missing a segment of road between Citilcum and Cacalchen. http://www.maps-of-mexico.com/quinta...o-map-a0.shtml

When I prepared for our trip to Santa Rosa and Uayamon back in September, I printed out the maps from the above website. Helped a lot, but I'd like a more detailed map next time.

Probably better directions:

If you use Google Earth, send me a PM. I can send you my file of various coordinates and towns in the area -- including all 5 of the Haciendas.

Signage to the Haciendas has been recently improved, it seems. Watch for little blue signs along the way. (I don't know for sure that these signs exist for San Jose, but they exist for the others.)
