We pick what cruises we go on based on the itinerary, and this itinerary (on paper) looked really great. Ultimately, the itinerary wasn't quite what we wanted, but the price for this cruise was really decent. Here I'm going to briefly talk about the good and the bad and what you can do to make the most of it.
Itinerary: Looks good until we dock in Freeport instead of Langelinie in Copenhagen, the far port in Helsinki, and an hour out of town in Stockholm. I'm sure this is why we got a good deal. Instead of spending money upfront, we spent it later to get to where we wanted to go.
Embarkation: The Dover port was a bit of a bottleneck. Make sure you have all of your papers ready to go. Grab a Sun Ship Map when you check in because you won't be able to find it on the ship.
