cave tubing question

[buzz2400]

I am trying to decide if I want to do this. Here is my problem. On long bumpy drives (which people state is about 1 hour one way) I tend to have to use the lady's room (even when I don't drink). Is the ride to the caves very bumpy or are they normal paved roads. When you get to the caves are the bathrooms right there are do you have to walk a little bit to get to them (because I read that you have to walk aways to get to the river).

 

does any tour guide use busses with bathrooms on them. How about carnival's tour?

The trip to the departure point for the cave tubing is a pretty smooth ride. When you arrive you have to take an old school bus up a dirt road for about a 5 minute ride. The larger buses cant fit the narrow road. There are bathrooms at the site where you get your equipment. There are no bathrooms along the actual cave tube route.
