A little time constraint, trying to do too much I guess.

Anyone know of a car hire service, or ability to rent a taxi for 2-3 hours?

I could rent a car for a few hours, but it'll be costly too. IDP ($20) + car rental (5200yen) + insurance + gas

Or try to plan my way around the train (30min Matsumoto-hotaka station, 10-20min can/bicycle)
