I went with my family to the Marriott on Sunday afternoon (19th April 2015) to have a look around. All the staff were beautifully turned out and very polite. We went outside to the swimming pool area and was told it was not yet ready for use, the outside Grill/Bar was closed and the staff were not sure when it would be open. The lobby is spacious but you can see it has not been cleaned as there were still wine stains on the floor, also some of the tiles seem to be cracked. The furniture looked like it had been moved by people who had dirty hands and had not been cleaned.
The receptionists were pleasant and I was told the there was no SPA (a real shame as there is a lack of good quality spas in Georgetown) and the staff were not able to tell me when would one would be opening.

We then went to the bar for a drink and we surprised to see that a local beer (Banks) cost Guy $900 (on the street you can buy them for Guy$ 200) so a very heavy mark up. The bar person gave us the bill and it had a mistake on it (they had not charged for one of our drinks), This was pointed out to the staff and rectified (lucky I'm honest!).

At no point were we invited to look at the rooms or the other facilities available even though it was a new hotel, and there didn't seem like there were many guests staying, and I'm sure they would like to showcase what is open.

Can't fault the staff as they seem very well trained but we will come back in 6 months and see how things are progressing.
