I like the club level at the Poly. The lounge is two stories and very spacious. There are floor to ceiling windows overlooking the Seven Seas Lagoon with the Castle in the distance. At night, they pipe in the music for the fireworks and the view is perfect.
I have always liked the food offerings. The food tends to have a pan-Asian flair. One nice thing about club level at the Poly is that the lounge is accessible 24 hours a day. After the club service has ended for the day, you can still go to the lounge to read or grab a beverage from a well-stocked cooler.
