If you want to go by reviews on TA, go by the 99% positive on every Couples resort. There are always the impossible to please who will find a negative anywhere they go. I feel sad for people like that.
I think we may have had an issue or two in all our trips to 3 of 4 Couples resorts that we have been to over the years but the funny thing is, I can't remember them. Every trip we took to Couples has wonderful memories which erased those issues.
"When you go, you'll know".....and then you can return and write your own review which, I'm sure, will be a good one.
