I would love to do this cruise next year and your review is really helpful. Regarding Dublin would a cruise excursion be a good option or just not enough time to enjoy the city?
DH and I never had a problem dressing for dinner and going to MDR. We enjoyed it, however now as a solo cruiser I find it much easier to go to OVC as I did on a recent cruise most nights. I also didn't mind packing all casual clothes.
8th time coming up this spring. Third on Summit. A beautiful island. I love walking around St. George and Tobacco bay was great for snorkeling. Have fun!
