We were just on the 1/22 Eastern cruise and had to tender in St. Thomas. From the spot you get off the tender boats, it is only 2 or 3 blocks to you left (when your back is to the water). You could easily walk it.
On the other hand, where the other boats docked, it was quite a distance. That was about the only good thing with tendering, it dropped you right off in the middle of the shopping district.
