I'm going to put my 2 cents worth here. I'll start off saying Hard Rock is not now or will ever be on my radar as a place to stay. Not my style.
I feel bad for this resort. Broken pipes have happened elsewhere in Punta Cana from time to time. Sometimes you turn on the shower or tap and nothing comes out. The electricity sometimes doesn't work and same for the internet service. If you have water it may not always be hot when you want it. Ac is struggling to keep ahead of the heat and humidity and it breaks. Dominican Republic is NOT the USA nor Canada. It is a developing nation with less than ideal infrastructure. When things break they don't always get fixed in a hurry like at home. All too often parts aren't readily available and have to be ordered.
I'm posting this remind folks where they have booked vacations. Stuff happens out of the control of the resorts and it doesn't care if you're staying at a 3 or 5 star location in DR. Guess I'm saying cut HR some slack over their water problem. Next week/month/year it could be IBG, Majestic, Sanctuary or even Grand Paradise having water woes.
