Accomodation

Natal is a large tourist city with many hotels and pousadas (pousada is a simpler hotel or hostel).
You can find hotels very close to the symposium venue.
There are many all-range hotels in the vicinity of the conference place, with very competitive prices.
Participants can easily make their own reservation for accommodation using Booking.com and TripAdvisor.com.
Each conference participant is responsible for his own reservation directly with the chosen hotel.
