the first thing that needs to be taken into account when planning a trip to rio de janeiro for réveillon is that thousands of other people will be planning exactly the same thing - the city is an incredibly popular new year's eve destination.

for this reason, there will be a very high demand for hotel rooms, hostels, and apartments so booking way in advance is a must.

due to brazilian and foreign tourism, the hotel occupancy rate in rio de janeiro over the new year holiday typically reaches almost 100%.

many travelers book nearly one full year in advance, especially large groups and visitors planning to rent a vacation apartment.   

an important point to be considered is price, as rio de janeiro is not an inexpensive city, and over the réveillon holiday period prices for accommodations can easily double up.
