Went there 2 weeks ago, loved it. there was another group there but it is far from a Disney crowd. They left and my wife and i had it alone for a bit before we left. Be smart and you will likely survive your visit.

Bring bug stuff, you may need it... better to have it and not need it than to need it and not have it.

The trail was fairly easy to follow and marked OK, once you knew what to look for, faded blue spray-painted arrows. the trail was a bit of a challenge for my wife but she made it fine, just be careful and pay attention to your footing. Watch out on the trail for the clearly marked Manchineel trees which are somewhat toxic.

It's definitely worth the visit. I found my visit to the bubbly pool to be one of the highlights of our trip.
