Hi dpage, welcome to Cruise-Chat. Not sure what your fears are, but they do sound a bit strange. The bathrooms in the mini-suites are very nice size. It is a real tub in there. As for people looking straight into your cabin, even if you left the door wide open, it would be hard to see the entire cabin, unless someone stuck their head inside. If you're planning on spending your cruise in the buff, keep you door closed and curtains drawn and you'll have no problems. If you're planning on running around on your balcony in the nude, I don't think there will be many vessels at sea coming up next to you. Now there may be some crew members that might hang on safety harnesses to take a look, but that would be very rare
You are allowed to take one bottle of wine per person on board with you. Best wishes and I really hope you enjoy your cruise.
