Cheryl,
We stayed in Casitas 3. We were vry close to El Centro, so we thought it was a great location. We used the Casitas pool more than the main pool, so walking around to the other side wasn't a big deal. We really liked it there, much more than we liked CBR. Our room had a king bed (which we requested) and was quite comfortable. We really like the Pepper Market. No problems at all with check in - went quickly and smoothly. Also, the mousekeeping was great. Didn't seem to matter what time we came back to our room, it was always ready for us! Have a great time!
