Can we bring our own snorkel gear and stay down longer then 2 hours ? if you rent there gear is says you can only stay down for 2 hrs

Yes you can and I think 2 hours is more than enough... It's not much to see there...

Yes you can bring your own gear but.....I think the 2hr limit is more of a safety reason. The water stays a constant 73ish degrees. If you're in that water that long some hypothermia could set in along with muscle cramps....Trust me even when Iwas in a wetsuit scuba diving i was ready to get out after an hour.
