I'll chime in here as we recently spent 43 nights on Mariner and 27 on Voyager. In both cases - yes - 830-ish arrivals generally mean the "early birds" have flown the coop by then. That's what we prefer especially if the 930pm show is not of interest to us.
We were on Mariner from 9/21-11/3. Never a problem getting the port info sheet when I asked for one. Rene and his staff were always quite helpful to us.
Those are available at Destinations but you have to ask for it. Not a stock of the printed copies - they will access the port info sheet you want on their computer and print a copy for you. I generally do this for ports we'll be in on Sundays to get close-by church info.
Depending on where in the world you join the ship - the request should be submitted anywhere from 60-90 days prior to embarkation. You need to specify exactly what you want .... and how much..... and it's possible that there will be a charge associated with your request depending on price and availability.
The wines onboard can vary from ship to ship depending on sourcing availability and where a ship may be taking on provisions.
Ex; Villa Maria as well as Pouilly- Fuisse(sp) were AWOL the last several weeks on Mariner. BUT we had a great red from Portugal-Escada, as well as a Red Blend from R Cellars
