Hi! We are booked on Adventure in September. Been to St Croix but not Tortola. However, it’s a really good itinerary especially for beach lovers and I have not heard anything about Adventure that concerns me. We have been on Mariner multiple times, it’s a great ship and one of my favorites. Went to Bermuda last year but it was on Celebrity. It had a much better itinerary than Mariner and our time in Bermuda was longer. I hope this helps in your decision but I’m sure no matter what you decide you’ll have a great cruise!
