First of all, if they are next door to each other, why does Tripadvisor list Riu Jalisco under the Nuevo section but Riu is under the Tenacatita section?
If you stay at either resort are you entitled to use the facilities (pools, restaurants, etc.) of both?
How do the rooms compare in size, cleanliness, luxury?
How do the pools compare?
If we choose Riu J. we get a $39 refund but if we choose Riu V. we pay an extra $260! Is Riu V. worth the extra money?
