High Standards, Spacious Rooms, Stunning Views, Convenience

JW Marriott Hotel Sanya Dadonghai Bay is located nearby Donghai Bay, the most popular beach in Sanya, and is embraced by lush, green tropical mountains offering stunning views of the mountains and ocean. The property is adjacent to a nationally protected natural coral reef, and its strategic location offers exclusivity while at the same time being just a five-minute drive from downtown. The hotel comprises two hotel towers—West Wing and East Wing—which are bridged by a cavernous main arrival hall. Upgraded in 2018, the JW Marriott has the newest conference facilities, services of the highest standard, and spacious rooms with great views. It is a few steps from a famous boardwalk with nearby high quality restaurants and bars, only five minutes to the city center and 30 minutes from Sanya International Airport, and is one of the closest international hotels to our local host IDSSE‘s facilities.

Please visit the JW Marriott Hotel‘s website to view images and videos of this location.

Bilingual Services

In Sanya, mostly Mandarin is spoken in hotels, restaurants and other public places. We recommend that you download a translation app for your phone such as Google translate, which will greatly facilitate communication. JW Marriott has an international English-speaking management team who have been fantastic to work with and will be available to resolve any issues and answer questions. While many hotel staff members do not speak English, we are making arrangements for volunteers from the local University English graduate program who speak both English and Mandarin to assist our participants with airport transfers, conference activities, and VIP guest services.

IMMS and IDSSE will also provide professional translation during the general sessions, thus enabling more Chinese participants to understand the presentations given in English, Chinese presentations to be translated into English, or for other language speakers to answer questions raised by Chinese participants.
