I am not aware of any traditional "crashpads" in GUM but a few pilots do rent out rooms, myself included, with furniture, etc included. Most of these rooms start at about $600/mo including utilities, etc. You will need a car unless you stay in a hotel. There is one building in Tumon I refer to as the "Pilot Ghetto" with about 10 of our FO's living there. They are 2 bedroom units @ $900/mo but I am not sure bout furnishings, utilities, etc.
