Jim,
June and I saw a travel show recently that featured Hamburg. One of the things mentioned on the show was a harbor cruise. From what June and I saw that looked like another option to the hop on hop off.
As you may recall June and I are booked and doing a back to back, going on to Lisbon from Hamburg. We thought we might do the harbor cruise while in the port for the turnover.
See you and Jan in August. Lookin forward to a great cruise with super cruise friends.
Ralph
