There's not much to keep you dawdling in Campo Grande. Those who are booked on package tours to Bonito or the Pantanal can time their arrivals to connect with their transfers onward, eliminating the need to stay in Campo Grande for a night.
Because of the distance and the difficulty of access, there is no 1-day option for the South Pantanal. Either commit to 3 days, or don't bother to come. The Refugio Caiman is one of the best ranches in the South Pantanal and a wonderful, cushy way to explore the ranch land and see some amazing wildlife. If you have a few extra days in this region, consider a 2-day side trip to Bonito to swim in the crystal-clear waters of the Rio Prata or Sucuri, and maybe try some rappelling or caving. If you need to spend the night in town, try to book a room at the Bristol Exceler Plaza Hotel, Av. Afonso Pena 444, Campo Grande (tel. 067/3312-2800; www.bristolhoteis.com.br). This hotel offers top-notch amenities including tennis courts, a swimming pool, and a sauna. The rooms are spacious and comfortably furnished, with tile floors, firm queen-size beds, and a small desk area. A double room goes for R$170 to R$200 (children 7 and under stay free in parent's room).
