Having just returned from a cruise myself, I'm only just now finding and reading your cruise review Kuki.
Enjoyed very much reading along with you on your Veendam cruise, and found many similarities on my own Noordam cruise.
The "No-access, no -tray" business in the buffet led to big line-ups, but eased off after the first day or two when the ship scored a 100% on their cleanliness check. From then on, we were allowed access to the drink station, and to a certain extent, the food, although most was still served behind glass barriers.
After reading your review, I'm intrigued to visit Bermuda, as I've never been there before, but I think I will avoid trying the Segway!
