I'm staying at GR Solaris in January. I read somewhere that you can pay a fee and visit the Gran Caribe or The Royal Solaris. I understand that if you are already staying at the Gran Caribe that you can visit The Royal Solaris provided you are staying in one of the suites at the Gran Caribe.
Has anyone that has stayed at the GR Solaris visited either of those resorts, and if so, what was the fee?
Has anyone ever just upgraded straight from the GR Solaris over to The Royal Solaris for a reasonable price after your arrival?
