We did this last week. We were off the ship by 7:15 and it is about a 10-15 walk to the port. Pay for the ferry ON the ferry and masks are mandatory. They will not give you one if you don't have one, so be prepared. I think my husband and I paid around $75.00 round trip, which included transportation down to the Baths and back to the ferry port. They will give you a wristband to wear so they know you have paid. We had no trouble making the 11 am shuttle back to the port for the 11:30 ferry back to Road Town. I will say that going through the Caves (the major attraction) took FOREVER (it was extremely crowded, and you have to wait in line) and I was starting to freak out a little, but we made it through with plenty of time to spare. It was not hard to do on our own, and definitely worth the trip. Have a fabulous time!
