Watch in HD. This is a DETAILED review of the Deluxe room, the lowest priced option available. The pools are OPEN during the winter months – all year round! Many hotels close them but ARIA keeps them open. The heated pools are awesome. There are a total of four pools. One large heated pool and three small spa tub style pools with powered jets! Towels are free downstairs (as many as you need). There is a $25 PER DAY resort fee per room, added on top of your reservation cost. This covers your cost for pool and gym use, as well as high speed internet (unlimited) in your room.
