We were on the Golden 2/7-2/14. We had a balcony cabin on Caribe (C612). I heard midship was a good location; the rocking motion is at a minimum.
Husband and I don't care for shows. We attended one, just to see what it was like. The singer was ok, but he was so 30 years ago that we left after 10 minutes (the 1970s.. been there, done that!). We much prefer to listen to music in the lounges, or dance to a combo. Shows consisted of singers, dancers, a magician and a comedian-juggler.
I've never been to the Caribbean in June, so I can't tell you what the weather was like. We went to the Eastern Caribbean. The temperatures were in the 80s and 90s.
Have a great time!
