When we came to check in at 3pm our room was not ready. We had to wait until 4pm until our room was ready. I might expect this of a 3-star hotel but not a 5-star hotel.

We booked the Unlock singapore package that allowed us to use the spa facilities free of charge. When we went to the spa it seemed we could have just used the facilities without using the package as nobody asked for our room number or name to confirm if we could use the facilities.

At breakfast we were assigned a table after collecting our food from the buffet bar, we went back to our table to find somebody seated init. We informed a waiter and they went to speak to the gentlemen but they didn't move him instead the solution was to find us another table in a full restaurant. I would have expected the staff to be more firm and remove the gentleman that sat at our table without been assigned it, as this was not our mistake.
