Dive glove prohibitions are quite common all around the world at warm water dive sites. Don't bring your gloves with you, when you go.
A hood is nice, sometimes, if you find yourself starting to get cold, even in 80F warm waters. So it is always good to bring a hood with you, just in case.
I have never had a problem bringing a dive knife with me anywhere. Mine is attached to my HP hose. And it must go into your checked luggage, needless to say. I always bring my knife with me, and since it is not a machete, no one has ever noticed it.
Only once in my diving career did I ever not have a knife with me on a dive, and that was the precise time that I got caught in fishing line, and my buddy swam off and did not notice I needed her help. It was as if God was teaching me a lesson, saying, "Dude, if you want to do high risk stuff, like scuba, make sure you have a dive knife with you always, and otherwise dont bug me with your prayers, Dude."
You can call ahead to the dive operator if you have any particular questions. That is something that I always do before a trip as well.
