Don't see how that would be possible - maybe some real small Silverseas ship might fit on the shorter section of the pier nearest the island - thou that's another thing that I don't think has ever happened.
Add the SetSail pass to the Apple Wallet - that will automatically decode the barcode on it - the decoded numbers should be <res number> - <cabin number> or <GTY> if still unassigned. If not on Apple, use an app or site to decode the barcode manually.
You still have some time - this will likely fix itself before the sailing and you'll get your assignment. Wait a couple of days after that for the docs to update to get the proper luggage tag.
That may be, but the reality is that other than perhaps folks with vision problems, no one has ever reported that ever happening since the pier was built.
You might get a slight break in price if you search for two - solo searches often eliminate the GTY offerings which are usually cheaper. In very low demand times, some O class cabins could be had for less than the usual 200% solo supplement - those may or may not come back.
Not in their SEC filings and have not found them separate anywhere else either. The financials are for the entire RCG, which includes Silverseas and RCG stake in other lines like Tui.
That feature (along with Favorites) on the website has been on and off for the past couple of months. The sailings which you add to the watch list are just listed as a convenience - no messages. Not sure what the long-term plan or functionality will be.
