My husband and I went to El Secreto for our one year anniversary. The hotel is stunning, and extremely private. We felt like we had the entire resort to ourselves. The staff were very attentive, but stayed in the background until you needed them. The grounds were stunning!! Every angle was like a post card. I had pretty high expectations but was very happily surprised. There were a few minor issues, we had trouble getting our hot tub turned on, out of the 7 nights we were there it was only turned on once, although we requested it every afternoon. Because of the time of year we went, the sand flies were quite bad (after the rainy season). The hotel did the best they could, and provided bug spray in all the rooms. In another couple of weeks they should be gone.
We were looking for a place that we could escape the world, and found it at El Secreto. We still participated in the activities that we wanted to, but enjoyed the peace and quiet the most!
We will definitely be back, and will highly recommend it to others we know who are thinking about Belize and Ambergris Caye as an option for a get away.
