ORLANDO — Universal Orlando plans to build a 4,000-room mega-hotel as part of its new Universal’s Volcano Bay water park. Universal Orlando will already have 6,200 on-site rooms once its new Aventura hotel opens in summer 2018.

Reports from multiple Florida media sources say Universal Orlando has filed plans with the city of Orlando that include a large hotel split in two across Universal Boulevard, on the old Wet ‘n Wild site which closed on Dec. 31, 2016.

Universal’s Volcano Bay is scheduled to open May 25, 2017 with 18 attractions in four themed areas on 28 “fully immersive” acres, says Universal Orlando. The park is centered around the 200-foot-tall volcano Krakatau.

Universal Orlando will have six on-property resorts when Universal’s Aventura Hotel, currently under construction, opens in summer 2018. Aventura is being positioned as an “affordable-chic” resort experience. The 16-storey glass tower will consist of 600 guest rooms, including 13 kids’ suites.

Aventura will neighbor Loews Sapphire Falls Resort and will be steps away from Universal Studios Florida, Universal’s Islands of Adventure and Universal’s Volcano Bay. Aventura will bring the total number of on-site hotel rooms at Universal Orlando Resort to 6,200 in 2018 when combined with the 400-room expansion of Universal’s Cabana Bay Beach Resort.
