Hiring a car is not that expensive, especially between two people, it will certainly give you far more time actually birding and you can stop anywhere you want on the way.
Sure, car hire gives a lot more flexibility and saves time when visiting multiple sites in a short time, but I figured since the OP was considering staying in one place for the week it seems car hire would be unnecessary - even with PT one can get to a range of great spots from San Jose in just a couple hours.
