No. They change it up every cruise depending on the number and distribution of guests. On our last cruise, we went to the MDR for embarkation lunch and checked out where we'd be sitting since we knew our table number by that time. When we went that evening to that same MDR, it was in a different place completely. It was still a 4-top but no where near where it had been that morning. So it appears that they rearrange after embarkation lunch. We've also never been anywhere close to where we'd been on a previous cruise. We've also been seated at tables for 4, 6, 8 and 10.
