Thanks Ken. Our original plan was to stay in CT for 2+ days and take our time visitingg each of them. However, our plans changed and we're now staying in Portovenere for the 2+ days.
So now the current thinking is to take the first boat in the morning to Monterosso and work our way back through each town until it's time to catch the last boat of the day, and we'll see how far we make it. If we can't get to them all in that one day, which seems a bit aggressive, then we may go back for a half day visit to see Riomaggiore and whatever other town we didn't make it to.
The description of each town all sound so inviting, so we don't want to miss any of them :) But I'm afraid we might have to narrow down the selection given our time constraints. Still trying to think through this.
Anyone have thoughts on the topic?
Also, if the boats aren't running due to rough water, or we want to stay later than the last boat, is the bus option a reasonable choice?
