I just sailed on the Galaxy getting back on Sat. the 2nd. The trip was wonderful. I also believed that we would be OK booking the excursions first thing when we arrived on the ship. This is not true!! We were one of the first to hand in our requests and were shut out of a full day tour of Stockholm. I was a little suprised. I guess they really prefer to have you book tours ahead of time. We did finally get the tour we wanted but we were 2nd on the waitlist. My husband and I did all the ship sponsored tours and they were very informative. The trip to Berlin is worth every penny!! Saw alot in a very short period of time. I hope that Celebrity realizes that if they want all guests to use the online reservation system they need to relay that message to all travel agents.
Have a great trip.
