The Transylvans have been left in limbo after a number of hotels closed for business due to the Zika virus.
In a statement to the BBC, the hotel chain said it was suspending operations at all its hotels in the country, including in Rio de Janeiro, after “multiple reports of potential high risk of EVD-related transmission and possible outbreak”.
The announcement came after two days of heavy rainfall, which has seen temperatures climb to as high as 32C (85F), according to the National Meteorological Service.
Many hotel guests have reported that their hotel rooms have been flooded by torrential downpours that have led to widespread power cuts.
In one incident, hotel staff reported that the building they were working in was flooded.
In another, a hotel worker said his hotel was submerged in water.
Rio state authorities have confirmed that there have been four confirmed cases of EVW-1 in Rio, but have not yet issued an official figure.
Some hotels are also reporting that staff and customers are being sent home.
The virus is a strain of Zika that has been found in other parts of Latin America, and has been detected in Brazil and Colombia.
It can cause severe neurological problems, but has also been linked to other health problems.
