Cozumel zipline

[Spencer71]

Will be on RCL in April with my 14-yr old daughter with stops in Roatan, Costa Maya, Cozumel.  Her #1 priority is to snorkel, so I figure best place for that is Roatan.  The only other thing she wants to do is zipline.  Doesn't seem like there is anything in Costa Maya, so I'm wondering about doing it in Cozumel.  I found an article that suggested Roatan has better ziplines than Cozumel, but I worry about giving up precious prime-location snorkeling in Roatan.  A few questions may help me sort it out - 

 

1. Anyone know if the zipline at Chankanaab is still open?  I can't seem to find much info about it, even on their website.

2. How does Awesome Flight Cozumel compare to Chankanaab for the zipline?

3. Instead of ziplining in Cozumel, would I be better off just doing a snorkel/zipline combo excursion in Roatan and then find a place to snorkel in Cozumel?

4. Are the ziplines worth going to on the mainland (eg. Xenses, Xcaret) compared to what's on Cozumel?

Zip line in Cozumel is basically flat.  Best place on your cruise to zip line is Roatan.  Many great zip lines there.

What zipline did you end up doing?

Ended up doing one in Roatan, not Cozumel.
