I've stayed all along the beach in Cabarete and having stayed at Millennium a few times, I noticed I wrote a review years back and it's as great as ever.
Millennium is a perfect location - right on the beach, centrally located and a short walk to the strip of restaurants and bars on the beach or up to kite beach. Though you can kite right in front. Another super big plus for Millennium is that if someone in the group isn't a kiter, the pool in front is beautiful and right on the beach, so you're enjoying the ocean and the action no matter what you're into.

The onsite spa is excellent. The restaurant attached to the hotel, Yalla, is consistently great and I'll post a separate review.

A big thanks to Meghan, Estebania, Kiko and the rest of the team.

Meghan went out of her way to look out for us and I saw that she does this for all guests which is something really fantastic! Especially as this was during a super busy holiday week.

One other tip is that the hotel is set up with excellent drivers. Meghan set up a car for us as we were arriving in Santiago, and one of the guys they use, Ramon, could not have been better. This is important when arriving after a long day of travel.

Our first time visiting Cabarete and Millennium! A small town feel with amazing beach front restaurants but without the busy tourist activity! We realize it was low season but our first vacation that didn’t feel over commercialized or the typical tourist “trap”! Highly recommend this area generally and Millennium specifically!

Stayed just after hurricane Fiona and the staff was very helpful. The hotel is very modern and comfortable and everything was functioning. Just a couple of constructive comments: you almost had to be a body builder to open the sliding glass door (apparently needed lubricant) in 223. The fact that there was a "toaster oven" instead of a microwave was curious. Not much you can do with the former and a microwave is so good for reheating, etc. Yalla, the hotel restaurant, is in a separate building, so at night you'd think there would be extra efforts to assist the visitor to go out there. Instead, the lighting in the walkway under the arbors on the side of the building was off and it was very dark. The lighting on the path directly out the back of the hotel is weak.
During the day, the chrome hand rail going up the stairs to Yalla is scorching hot - no warning and no cloth or other material to protect the user.

I have disabilities but could have used the stairs in the hotel except for the fact there are no railings. I may have had quite a difficulty if the electricity was out or if there was some other emergency. Railings are essential.
