For the main dining room, dinner hours were 7-9 pm and it was open seating. They also serve tapas in the evening at the Bistro occasionally and you can make a reservation with your Butler. The Vintage Room is the private dining room for purchase I think it seats 10, I’ll double-check. As Ngaire said I’m out sick and my notes are at the office. There was one evening in which they took us on an evening tour so there was an early dining dinner buffet. We arrived at different times and dinner service was always prompt. We dined with others a couple of times but there was plenty of seating for just two if you prefer. It was exactly like it would be on Regent. No pressure to arrive at a certain time.
