Took the guided tour (as opposed to the wild "crawing-on-your-belly" tour). My in-laws came along to hold the girls hands while S and I held hands. Caves are romantic, what can I say.
Some interesting factoids:
Speaking of bats, we did get to see two of them while spelunkering around inside the cave. C was more excited than scared as she traversed the sometimes narrow, often tight, and always slippery walkways. Not having to bend and stoop over when the rest of us had to duck walk through some low lying alabaster crevice, made her journey much to her liking.
Meanwhile, her barrage of questions to the Park Ranger/Tour Guide were typical of a 5-year old, but provided audible entertainment to the few who were on the tour with us. Some questions I recall her asking follow:
How are they made?
Do you live down here?
How come people are afaid of bats? I mean, I'm afraid of them, but that's only because they're kinda scary. Don't you think they're scary?
What is that writing on the wall?
Can I take some cave home with me?
Hey, not everyone can get a Park Ranger to blush.
