I didn't check your sailing date, may be all important? A bit early to predict, I guess. As for excursions, if at all within your budget book them. Chances are you'll want the fresh air & time on land. I lean heavy on the exercise, gym mornings. Sauna, pool time, hot tub, still my all-time favorite is 5am coffee and quiet sun rises! On the ocean, unbeatable. And, I miss those so much between outings. Bring some Good Reads, relax, don't worry about services, the best company you'll ever find will be family. If lucky your dinner party also! Be chill ?
