Quick verdict: Worth it, with a caveat.
Tubing at Rainbow Springs was an enjoyable outing overall, but there was one practical issue that stood out enough for me to mention afterward.
The exit
Getting out of the river could have been easier. My main criticism was that the exit area needed a better place to stand while climbing out.
That may sound like a small thing, but when you are wet, carrying gear and getting out of moving water, footing matters.
Would I still do it?
Yes. The issue was not enough to make the overall experience bad. It was simply something I thought could be improved.
Worth It Scout verdict
Worth it, with a caveat. The tubing experience itself was enjoyable; the exit was the one part I would change.
My original takeaway
Exit needs a place to stand while getting out of river.
