Well I just checked the whole Real Hotels website
http://www.realresorts.com.mx
and the dates I put in were 12/20 - 12/27 the only days that you paid for were the 20th and 21st. It was for all the Real hotels in the area. I did a reservation quote for 3 rooms for 10 people 6 adults 4 kids and it came to a little over 2000.00 (That is for the Gran Porto Real)all together! for 1 room I think it was about 800.00 and it's AI and it's right by 5th.
