"Tip: Join Imperial Club International—membership is free—and you can use the pool and gym for free and get other hotel discounts"

"The original structure was built in 1890 and was expanded to include two towers and a number of amenities including an indoor pool, spa and salon, and on-site child care"

"The tower’s 20th floor houses a lap pool, gym and sauna"

"A gym, small indoor pool and saunas constitute the health club, all for a fee (though those who become members of the Imperial Club—membership is free—can use the pool and gym for free)"
