Here's what OP posted on Tripadvisor:
Dive Paradise:
+ positives
Reasonable price, always on time, skilled/knowledgeable dive masters, flexible
-negatives
Again, the story always changed depending on who you talked to. Huge communication barriers--we booked the reservations with Kathy (she's in the US), but when we got to the shop no one seemed to know who we were and communicating was very difficult. Boat staff was not as helpful as I would have liked. Some dive masters didn't point out as much as I am used to while diving.
Doesn't sound like anything concrete to me, and a bit different there than what was presented here. I've been diving with DP for over 20 years now (we are "co-termed" in Cozumel...lol) and I have had a few "experiences" with somewhat inattentive divemasters (who hasn't wherever they are?). However, I'd personally give DP a 9.5/10 every time, but I am also personal friends with Apple, and always pay extra for the fast boats and EDP trips and all that, so my experience may be somewhat different than others...also, being on "his first dive trip since being certified" I don't know how this newbie would be in a position to rate a dive operation as well-known and long standing as Dive Paradise, having no real experience across the board or anything with which to compare it. Likewise, I don't know how you could be "used to" any actions of a divemaster having only had your certification dives...On the other newbie thing, I don't accept my students ever dropping weights or failing to secure their equipment. This is a basic tenent of diving. Also, what if there was another diver under that falling weight? Bonk! So, while I appreciate "the share" from the other commentator, I don't agree with their view (although will defend to the death their right to present it)...
Finally, we all need to take these negative commentary posts with a grain of salt, especially when being made by "new members" because there is a bit of "sniping" on the board. By that I mean that these phantom new screen names pop up, the negativity is deposited and then for some reason the poster is never heard from again...one can only wonder who is really behind that...
