Please don't be too concerned....that's the downside of reading reviews. They are based on opinions and they are anonymous. Of course you don't have to believe me any more than you should believe the negative reviews, but I just returned from SERC on Sunday and I can honestly tell you there is nothing to be concerned about. You will not be disappointed with SERC. I have not had a chance to write my review yet, but I assure you when I do it will be very positive. People are happy there. People are having a great time. There is not mass illness, while I in no way mean to discount the fact that yes people did get sick - it does happen and will happen in foreign countriesl This was our 4th time the Mexico and the sick issue was less obvious in this resort than others. Meaning the "talk" among the guests was much less here than other resorts we've stayed at.
The staff was amazing. Some of the most attentive waitstaff we have met. They were wonderful. Not one rude staff member among them. The grounds are beautiful. The pools are spacious and kept clean. Pleanty of chairs. Sure you may have a float issue, but that shouldn't be enough to ruin your vacation. Yes there is sea grass, but the beach is still beautiful, lots of chairs and it's a good size. The hobie cat rides are great fun!
The floors in the lobby are marble type, sure they can be slick if wet, and the pools have stone around them, sure if wet they can be slick too - use common sense - don't run, walk. Anyone could slip. I read the exact same comments a year ago on a different forum for a different resort in Mexico as well. Actually, I've read much of these negative reviews for any resorts - read for yourself. The negative ones will stick out in your mind over the good ones.
I guess what I'm saying is that PLEASE - don't let it scare you. Please don't cancel your trip. Go and enjoy. Your vacation will be fine. Don't look for the negative. Enjoy the resort. Enjoy the staff, enjoy the country! And try to relax! If you have any questions, let me know, I'd be glad to try to answer them!
