The DR can be a great trip. Been there 4 times, each time back at the same resort (Barcelo Bavaro Beach). We went there on our 25th anniversary trip in 2019. Wasn't our first choice for that trip, but extenuating circumstances kept us from going back to Maui that year. Actually was a really nice trip, and had a very good private anniversary dinner on the beach, while watching the moon rise out of the ocean. Most of the restaurant choices at the Barcelo are quite good, in contrast to what I hear about other DR resorts.
We were back there again last fall. Interesting thing is that after our first visit there in 2015, there are a few of the staff that have remembered us each time we have gone back. As in, greeted us like old friends. I don't think we are that memorable, and we aren't throwing Benjamins around as tips, either. Yes we do tip, just not like that. We've also heard that the service is not so good at other DR resorts, but we find the service there to be on par with the best we have received in Riviera Maya.
We should probably try another DR resort, but there is something about the Barcelo. We've been to at least a dozen different Riviera Maya resorts, from Cancun Hotel Zone all the way to Tulum (well, almost) and have only returned to one, the Valentin Imperial. That's another great resort, but its getting really pricey.
