We usually do all ou own excursions. we are on the Dawn in three weeks and have booked a full day in St Thomas with Winifred . A full day on their yacht. it's a maximum of six people and is cheaper the Princess. However this year we have booked three trips with Princess. All sports related,just for the guarantee of safety and insurance. we will do averything else ourselves. I would never consider any land trips with the cruise lines. You can do them yourselves for half the price and at your own pace, just team up with someone else on the ship.
