There are a total of 5,986 rooms from 13 Metro Manila hotels are available for leisure guests or “staycationers” from the National Capital Region and neighboring provinces of Bulacan, Cavite, Laguna, and Rizal—known collectively as the NCR Plus.
Subject to the observance of minimum public health standards, these hotels have been granted a certificate of authority to operate for staycations by the Department of Health: Grand Hyatt Manila, Okada Manila, Shangri-La at the Fort, Nobu Hotel, Joy Nostalg Hotel & Suites Manila, Edsa Shangri-La, Solaire Resort, Hyatt Regency Manila, Nüwa Manila, The Peninsula Manila, Aruga by Rockwell, Sheraton Manila Hotel, and Hilton Manila.
“While the IATF allowed our request to permit leisure travel under the current quarantine condition, we would like to remind everyone that the health and safety of our guests and tourism workers remain the utmost priority. These staycation hotels, all of which are star-rated, have the capacity and have been inspected and oriented on the new normal protocols to ensure this,” Tourism Secretary Bernadette Romulo-Puyat said.
Staycation guests must only come from within the NCR Plus area and must not be below 18 or above 65 years old.
IATF Resolution No. 115-A allowed the “specialized markets” for tourism to operate even while the NCR Plus or the Greater Manila is under general community quarantine with “heightened restrictions”, subject to minimum public health standards. This implementation allows the staycation and point-to-point air travel for leisure from “NCR Plus” to GCQ or modified GCQ areas.
The tourism agency assures that these hotels are not being used as COVID-19 quarantine facilities.
