Thank you Tasha and Angel for this information!
I'm working with a travel agent now, that I've used through work and he actually just got back from the Iberostar Rose Hall Suites on 12/29. He said that the suites were nicer because you had unlimited access to the restaurants, whereas at the hotel you're limited to three nights a week. But it is more expensive. And all the rooms are at least junior suites.
I'm going to have him price out both and then compare the two. I think if people are only there a couple nights the limited restaurants wouldn't really matter...
