We are cruising this summer and will be going to 8 different ports. We will have plans for 2 of them, including a private tour for at least one. However, it's been a little overwhelming to figure out excursions/tours for the other 6 ports. Is there a way to find out if any of the ports disembark within walking distance of towns/sites so we might not have to have anything scheduled (the ports include Inverness/Loch Ness Scotland, Glasgow, Belfast, Holyhead Wales, Cork Ireland, and Dover England
