Wonder, don't let that deter you at this point in time. Most people who ever take the time to give guest feedback are those who have something negative to say. Most of them are just very hard to please people whose standard of living just rises when they leave home. Go there, have a ball, do lots of things, have a few vino's, and at the end of the day collapse in a happy heap in bed.
If there is something wrong with the resort, state very nicely to the resort people what the problem is, and I am sure they will bend over backwards to help you. Its amazing how magic can happen when people are nice.
Note: I don't work for the resort, but I am in the accommodation business
