Traveling as a single, I try not to take a table for four but generally if it's busy people will ask to join me and I say fine. In recent years, I've noticed the card playing, readers, crossword puzzles, etc. using the buffet area.
I don't get it when almost all ships have areas with views for cards, reading, etc. I think I noticed it more on the Summit because that ship was very short on windows and places to sit with a sea view.
I've sat with people who got up and left which becomes their problem and not mine. I refuse to balance a tray of food in a lounge chair! I haven't been on one of the bigger ships yet so I'll be curious to see what it is like on the Golden at T-time. Sue
