I really enjoyed Marriot Tampa Airport. I stayed there one night coming from Mexico City via Houston and I continued to Milan via Philadelphia the next day (17 April).
When I arrived the sun was still shining (around 6 pm), and I first visited the pool area and spent some 10 minutes in the hot tub. It was so relaxing.
The restaurant has a revolving restaurant on the top. It was great! I watched the sunset whilst eating sushi.
