We just completed a 12 night cruise from Amsterdam to Barcelona on the Voyager. Here is a brief synopsis - using Silversea (Spirit), Crystal and Princess (Diamond) for comparison. For perspective - you will find me in the gym, bar, restaurant or casino - not in the lectures, shops or shows.
1. Getting on and off is very easy - just like any similar ship. I can't say the same for Princess or similar lines.
2. Cabin - very comfortable bed and pillows, good staff and quiet - I like the Regent "touch" of offering bottles of liquor for the cabin. Good shower and water pressure - although the drain was slow when we first got on and we had to have it cleaned out.
