Breaking this into easily digestable sections:
The ship: Regals obviously looks pleasing to the eye but don't let it fool you, despite the fancy new atrium and attractive fittings is a flawed ship (see scores for Royal). It has tried to improve on the design flaws of the Royal with minimal success. There are NO midship stair ways resulting in overburdened central lifts that (I'm not joking) can take anywhere from 7 minutes to arrive and will stop (guarenteed) at EVERY deck, as people call them then give up waiting. Because of their excess use, the lifts were even inoperarable at times!
They are apparently suitable for 18, yes 18 persons! Not a chance, even with discomfort you could probably sqeeze in 12 and that's a push. It often gets so squashing in there it gets hot, and very hot very quickly which become increasingly infurtiating as you stop at every desk and no one gets in. More cabins added in increasing footflow and less accessways to compensate. Ridculous! I assure you after a few days this becomes very tedious! -----------3/10
