It could have been a very much better experience.
Pros:

The room was big and spacious and we had a very beautiful view of the city at night.

Cons:

We requested for a later check out and was given 1:30 p.m.

Then, when our tour operator informed us of our return timing of our morning tour, I asked for an extension of the later check out time to 2 p.m., but the counter staff very sternly rejected my request.

On the day of our check out, we rushed through our washing up to reach the counter by 1:30 p.m. but there was a long queue of guests in front of us checking in.

By the time the counter staff processed our check out, it was around 2:10 p.m.

Wouldn't JW Marriot, being a top class hotel, allow for some flexibility in extending our check out time by 30 minutes?
