I have sailing many times with Princess and always had a good time. I was very disappointed with the Regal for many reason. Her cabins are much smaller than other ships and the balconies were very small, there is no outside promenade deck, there is no lounge where you could just sit and look out. The Wifi was very slow. I enjoy watching football however the games were only shown on the outside big screen. Not too bad during the day but to sit outside on a cold deck to watch a night game was not pleasant.
The ship is very pretty but too big for me. The food was good but not a good variety.
The entertainment was just ok. The production shows could have been better. The outside entertainers that preformed were excellent. The excursion in St Lucia was too long and the winding roads made it a very uncomfortable tour.
Emerald deck cabins are obstructed. The life boats and in the way of looking down and seeing anything. The cabin was much smaller than the other Princess ships I've sailed on.
