the staff are friendly and the whole process smooth. even if it's cold outside (we went mid-May so end of fall), the cave water is a constant temp, and they have tight wetsuits to keep you warm. they also have hot showers and warm soup afterwards to warm you back up.

there was a large friendly tuna eel hanging out when we were there so we got a pic with her.

you aren't allowed to bring cameras/phones into the caves (under the guise of dropping them is a huge pita to try and find in the darkness and crevices). while this is perfectly reasonable, especially as one of the guides will have a camera and can take pics as you go, they end up nickle&dimeing you at the end to buy the entire photo package for extra cost (and they aren't exactly cheap). so if you want any pics of your adventure, you have no choice. kind of a jerk move.
