My best friend and I are cruising together on your cruise! The Sapphire on 5/29/05! I just cruised on the Diamond Princess (to Alaska, no less!) nine months ago and had such a spectacular time then that I am cruising again! (To Alaska!) On the Diamond I had no problems at all with dining arrangements! Most times I made reservations without a hitch.
Also, there was no problem getting back onto the ship after visiting the different ports.
I had NO problems. Ziltch! Had a wonderful time on the Diamond Princess and am looking forward to the same outstanding service on the Sapphire!
