Reval Park & Casino Hotel is home to Estonia's largest casino, the Olympic Casino, where guests can have fun with a selection of table games that includes American Roulette, Blackjack, Red Dog, Baccarat, and Poker. Guests who prefer a more definite return for their money can treat themselves to a hair or beauty treatment in the beauty salon, or head for the bar for cocktails. Wireless Internet is available in public areas for those who wish to keep in touch with friends, while the more old-fashioned will find postcards in the gift shop. The old town, National Opera and Kadriorg Palace, which houses the Art Museum of Estonia, can all be found within two kilometres. Tallinnn Airport is five kilometres from the airport. Bus numbers 2 and 20 run from the airport into the city centre. Alternatively, taxis are available at the terminal.
