We have booked the GAS tour for June. This will be our fourth RS tour (and our seventh trip to Europe) and our custom is to arrive two days before the tour, so that we get over jet lag. Leave New York on Wednesday night and arrive on Thursday for a tour that starts on Saturday. Thursday is spent walking in the morning and napping in the afternoon before settling down for dinner on Europe time.
This tour starts in Trier. While it looks scenic, it doesn't really look like there's a lot to do there (and what there is to do is covered on the tour). With a full day Friday for light activity and almost a full day before the tour starts on Saturday, I was wondering whether it's worth it to stay somewhere other than Trier for two nights, then travel there on Saturday. Cologne looks appealing.
Also wondering whether it's worth it to rent a car short-term, one-way within Germany. There are three of us, and driving on the Autobahn is on my bucket list. I have driven on the autoroutes of France, and found it to be a pleasure.
Thanks!
