My biggest concern about the Ireland trip is rain. I know I'm just supposed to embrace the Irish rain—it's what make the country so green—but multiple heavy rain days on my Portugal and Village Italy tours made them less enjoyable/less comfortable than if the weather had been kinder. I am also not a fan of later group dinners (I am not used to eating late and I have difficulty winding down to fall asleep afterwards), which I imagine the France tour would involve. Late dinners paired with early next-day departures are tough!
I’ve taken both the Ireland trip (just completed) and Eastern France (in 2011) tours. The Eastern France itinerary has changed slightly since I took it as it now ends in Aix.
Eastern France - I really enjoyed this trip. I recall it seemed to be pretty laid back with a good amount of free time and there seemed to be less bus time than on some of the tours I have taken. I don’t recall dinner timing, but I rarely have dinner before 7pm at home so late night dining is a non-issue for me. Perhaps someone who has taken this trip recently can answer. If you enjoy wine, this is a ”pro” as there are lots of opportunities for wine tasting (e.g., champagne in Reims, tastings in Beaune during free time, lunch at a winery, etc.). If you don’t like wine, this might be a ”con”. There are some charming villages and spectacular Alpine scenery. There will likely be less rain than Ireland.
Ireland - Due to my injury, I had to sit out some of the activities, so I can’t fully judge the tour. I missed all of the activities in Kinsale (some people said this was the town they enjoyed the most), the walking tour in Dingle, the walking tour in Galway, and the Aran island visit. I find the history and music of Ireland to be very interesting so these were a highlight for me. We had two different performances by local musicians during our tour. I also enjoyed a concert at a church in Dublin and at a pub in Westport during my free time. One downside was that music in the pubs often doesn’t start until after 9pm. Weather was a factor. On my trip it rained during the Rock of Cashel visit, on our free day in Dingle, and the day of the Aran Island visit (which I skipped). The rope bridge was also closed due to high winds. However, weather is always unpredictable. Ireland had unseasonably dry weather earlier in the month this year. The scenery throughout the trip was really beautiful and I thought all the local guides were great storytellers. One of my favorite activities was the hawk walk. I’m a backyard birdwatcher and the opportunity to see a Harris Hawk up close was amazing; it is something I would have never done as an independent traveler. If you do take this tour, I’d suggest reading the book ”Say Nothing” and watching ”Derry Girls” on netflix. I had read ”Say Nothing” twice before my trip and it really helped to put the history of the ”troubles” in context during my visit.
I know this is a bit of a rambling response but I don’t think you can make a mistake with either tour. I’d just go with the one that sounds more appealing to you. Have you looked at the scrapbooks? I often find those helpful.
