Island Marketing or Carnival excursions in St. Thomas

[cruisefanatic01]

I'm debating on whether we should use Island Marketing or book through Carnival for excursions in St. Thomas. Has anyone been on any of the following excursions? Also, from what I've been told Island Marketing is only the middle man and that the excursions are done through different vendors. So I'm looking for answers specific to St. Thomas vendors.

 

Island Marketing - St. Thomas

1. Jetski Snorkeling Safari

 

Carnival

1.BOSS Underwater Adventure

2.Helmet Dive at Coral World Ocean Park

3.Screamin' Eagle Jet Boat

Hi, we didn't use Island Marketing for a Jetski Snorkeling Safari but we booked a Full Day Sail with them and were very pleased. Check out my review:
