Lynn and I have done 3 Transatlantic runs(Mariner, Voyager, and Diamond) and one 26 day Pacific(SFO-SFO thru Marquesas, FP and Hawaii aboard Mariner) with 16 days at sea. The first Transatlantic aboard Mariner from Tenerife-Bermuda-FLL in Nov we had a couple of days with moderate seas due to a large storm @ 1000 miles north of us( couldn't dance very well, but nobody got seasick ). From mid Atlantic on it was calm with temps in the 70s and water temps in the 60s. Second was on Voyager in Apr/May FLL-Monte Carlo thru Funchal. Smooth as silk all the way with temps about the same. The pool got a lot of use. Third was aboard Diamond Rome-San Juan thru Funchal. Had a few days with moderate seas, but nothing bad. The Pacific cruise was in late Sep-mid Oct and it was idealic all the way with calm seas and temps primarily in the 80s. We were never bored on any of the cruises. There is always something going on. The way RSSC pampers you, you won't want to go home.
