Cancun Royal Solaris - Questions

Looking for my first all inclusive vacation resort. I was told of the
Royal Solaris and the GR Solaris in Cancun. I was told that the Solaris
Resorts are good. Are there any in Cancun that are better than Solaris
Resorts? We also understand that at the GR Solaris all room have
balconys while the Royal Solaris only some do. We were also told that
the GR Solaris is smaller than the Royal Solaris and the GR Solaris is
more upscale. Any opinions as to which are better?

As I stated in the beginning, this is my very first all inclusive
vacation and I'm just beginning my research. I appreciate any and all
information. We think we are sure that Cancun is the destination we
want as we have never been but always wanted to go. A little background
information: Past vacations included 20+ Cruises plus land based
vacations (all beach destinations). Two guys aged 42 & 38 traveling.
Were not into night clubs but do enjoy bars and talking to other guests.
We also enjoy production shows. Casinos are a plus but we know there
are none in Cancun (that would just make it perfect). Thanks again for
any and all help & input.
