Grand Cayman tender questions

[ten822]

I heard that DCL excursions get off first. Does that mean 10:30? What's the latest? I guess it goes by your excursion time? Has anyone ever missed a DCL excursion?
I want to explore on my own but leaning towards an excursion to "guarantee" getting off at a decent time. Advice?
Considering the sensational reef snorkel and coconut joe's lunch. Is the reef worth it?

If you're just going to explore on your own don't worry - there will be plenty of time to catch a tender after the groups.
