There are hotels and other accommodation in the towns of Puerto Ayora, Puerto Villamil and Puerto Baquerizo Moreno, however if you really want to see lots of good wildlife, you will need to combine your stay on these islands with daily boat tours to other islands.
Hotels and hostels are available on San Cristóbal, Santa Cruz, Isabela and Florena from $25-$500+, while hotels along the water are generally full especially in Santa Cruz. During peak season Christmas & Easter weeks as well as during special events all hotels are frequently sold out well in advance. However, if you are traveling at other times of the year you may be able to find availability by just showing up.
