We just returned and the beach closure did have an impact. Although it appeared the beach itself was not closed, the access to the beach from the resort was closed between 9 and 5. We just went to the beach first thing in the morning and then after five.
If you are committed to going to the beach you could get access from another point or just duck under the rope but safety would be an issue since there were large dumptrucks and earthmoving equipment working right on the beach next to the resort.
While the beach access closure did have an impact, as it would have been nice to spend some "prime time" on the beach, it certainly did not ruin our vacation and in hindsight, I would not cancel a vacation because of it.
