We were on the same ship same Alaska cruise 8 years ago.The millennium has been revitalized and the improvements are very nice.The boarding of the ship was fabulous since we had preregistered on line they scan our phones and off to board the ship.We were sailing with friends of ours and it was their first cruise.We wanted to surprise our friends so we ate ate Qsine(which this was the next to last cruise for qsine as they were changing out that specialty restaurant and putting a different one in.Food was very good and the service was excellent they also took into account my gluten allergy which I appreciated.The next night we attempted to eat in the dining room and the service was soo bad drinks not being refilled dirty plates not cleared in a timely fashion we spent over 2.5 hours in the dining room and was not pleased.The food is not very good at all reminds me of Golden Corral restaurant or a cheap buffet.With my gluten allergy I was used to the Assistant madre d taking my order for the next night.Well it ended up that the assistant waiter who didn’t have a good grasp of the English language taking my order.My gluten allergy is a serious medical condition and on the Summit they took it very seriously but not on this ship to my dismay.The next few nights we ate at either a specialty restaurant or off the ship.I brought my concerns up to the maitre d on the next to last night on the ship and told him we will not being eating in the dining room again.The buffet was terrible also with one day my wife saw bugs crawling over the cheese...yuck.Our room steward did a wonderful job and we had problems with the air conditioning which took 2 days and 2calls to maintenance to get fixed.We specifically choose this date because my wife wanted to see the dancers from the American Ballet theater.We enjoyed the performance and the comedian on the first night.Service has gone done hill where I had to chase someone down for a drink and the workers did not seem to be happy at all.We saw 2 workers we had on our wonderful trip on the summit and they were ready to go back to that ship.We had several problems getting bartenders attention because they were busy talking to the pretty young ladies.Alaska is one our favorite trips to do but I need to think twice before getting on a Celebrity ship.
