This was a cruise from southhampton to USA. The embarkation was poor at southamption as to waiting times which was due to the way the queues are organised. The arrival at Boston took a minimum standing time of two hours to get off ship with queues stretching more than double the length of the ship to go through US customs; customs were quick; therefore the delays are down to RC. Similar delays were also on final embarkation of the ship. Again this was down to RC and not as claimed by RC due to port and customs. There is plenty of senior staff going around the ship checking on front of house staff and service. Front of house staff and their service was generally very good and the amount of senior staff are not required as standing around on phones/discussions do not assist the front of house staff or the service. More front of house staff and less senior staff would improve the passenger experience. i.e. there was a problem at the promanade cafe which saw 4 senior staff on phones and in discusions with each other. The addition of two front of house staff to serve the customers, then the kitchen could not keep up with the customers queues better if the seniors had actually joined the front line staff and back room to improve the service. Similarly the windjammer, certain dishes were not available for 15 minutes and front line staff having to complain on behalf of passengers. What dishes there were available e.g, sausages you could not get a knife through the middle and the ends were worse, this cannot be edible. At this time there was 3 senior staff checking the service in the windjammer. Possibly checking the product that was being served and assisting with service would have improved the customers experience.
