I have a couple questions about flying to the caverns..

1) How long should you stay? Can you see much in one day? Would you
get bored after 1/2 a day?
2) Do you need to rent a car or is transportation available?

I'm going to be in NM (Albquerque actually) to visit family. I was
thinking of taking off for a day or two and taking my boys (8 and 9 )
to the caverns.
