The Institute of Mathematical and Computer Sciences (ICMC-USP) (map) has a very good infra-structure. It is very close to the Praça XV, a central and traditional square of São Carlos around which the visitor will find a nice and affordable network of hotels and restaurants.
Two important observations:
1- Another big event will be held in USP during the same period as EBP, so it is better to book a room as soon as possible.
2- We have pre-booked (until june 30th) some rooms at the Hotel Indaiá Residence (map) with special fees, so do not forget to mention that you will participate to the Brazilian Probability School if you wish to book there.
From Viracopos Airport to Campinas bus station (Rodoviária de Campinas). We suggest to use Lira Bus (VB transportes). The bus schedules are given at this link (precisely the last 3 tables, entitled "Sentido Rodoviária de Campinas"). The trip takes approximately 40min. To buy the ticket go to the desk at the domestic arrival of the airport (less than R$15). Another possibility is to use the municipal line (Line 193). It is cheaper (less than R$5) but takes more time (50-60min) to reach Campinas bus station, and is less comfortable.
From Campinas bus station (Rodoviária de Campinas) to São Carlos Bus Station. There are two companies (Cometa and Empresa Cruz) to reach São Carlos, the trip is approximately 2h-2h30 long. We suggest to access the respective websites to make reservations and see the departure times. Currently, the buses of Cometa leave at: 6h30, 9h30, 12h00, 17h30, 22h50, 23h20. The buses of Empresa Cruz leave at: 6h50, 8h00, 10h00, 10h50, 12h50, 14h30, 15h50, 17h00, 17h20, 18h00, 20h30.
Here is a non-exhaustive list of hotels. All of them have rooms with wi-fi, cable tv, and included breakfast.
Naturally, it is easy to consult this link which gives an exhaustive list of restaurants in São Carlos...)
Anyway, here is a short list of restaurants, all at walking distance from ICMC (unless stated otherwise!).
