Here's a link to a map of the Riu Tequila :-

We stayed there 4 years ago and our room was in block 27 very close to the pool and a few minutes walk away from the reception/entertainment area, the map is slightly out of date but accurate enough to give you a good idea of where rooms are located
Here's a link to a google map of the area giving you a better idea of the location of the rooms to the golf course etc :-

Hope these are some use to you, we love the Riu Tequila and the other Rius in the area and are staying at the Riu Yucatan in 5 weeks time.
