It is very much like a fine restaurant. You are greeted by the Maitre 'd and tell him your table preference. If you want a "deuce"... ask for it... and be sure to tell him you wish to dine alone! No problem. Or, if you want company, so be it. You'll be seated with folks who have just been seated as well... so you'll all be reading menu's at the same time. If you find some people who's company you enjoy, you can request a table with them for the following evening, at any time you choose. It works remarkably well!
Just back from the Golden Dec 1 - 8. After formal dining twice before, we chose PC and will never go back. First night reservations for 2, second night reservations for 4, met new friend at the airport. The rest of the week we just showed up at the dinning room and asked to be seated at a large table. Every time we ate together as all at the table had been seated within 5 minutes. 5 nights x 3 to 4 couples = 30 new friends to talk to about our adventures.
