We went to the RDC last March for the first time. They put us in Block 4, main floor, right by the Vallarta Adventures Desk. We found it too noisy during the day, and didn't want the main floor and we also found the room to be quite small. It did have a gorgeous view though. We asked the next day to be moved. We switched to Room 6320, which was spacious and the view was beautiful of the pool and grounds. We are returning this March again, and are wondering about the difference in the rooms for Block 5 and 6. People have said all the rooms are the same, but they can't be, because we had a much larger room in 6320, than in Block 4. 6320 had the adjoining door, so we are wondering if the rooms with adjoining doors are more spacious, and the rest of the rooms are the same. We are also wondering if Block 5 is quieter than Block 6? Thanks for any tips on this before we go! Does it really help to email one week in advance to see if they will put your request for the Block or floor you want?
