The D Las Vegas The D (previously known as Sundance upon opening in July 1980, and then Fitzgerald’s) is the tallest building in downtown Las Vegas. The hotel is a 34-story building with 638 rooms, many of which are suites. There is also a pool and a 24-hour fitness center. The D sportsbook is run by William Hill, who set the Vegas sports lines for customers. All the Vegas sports betting odds for the day are shown on betting boards behind the cashier, or you can simply open a William Hill sports betting account and then download the app. Live betting is also available in the Sportsbook. The Sportsbook has eight standard TVs and there is limited seating and a couple of high tables. Another interesting feature is the Bitcoin ATM next to the gaming floor, where customers can buy and sell Bitcoin instantly for cash.
