We booked Golden Heron tours through a package with The Crow's Nest. It made no mention of health limitations, or the conditions of the Kayaks.
This group is not well organized and runs a slo\ipshod trip. Do not book this trip that starts at 2PM and ends around 8:30. Instead, go on the motorized boat that is much shorter duration.
You will be able on the motorized boat, to go swimming in the biolumenescent bbay without having to slide off a kayak in darkness and having to board it in the same darkness.
I have a heart condition, but am active; combine this with a boat that had terrible suppport (missing cleats), it was a BAD experience!
