We have stayed here numerous times and we are writing to say there was an improvement and share a couple tips.
We stayed here New Years and given the time of the year and date it was a great stay. The food and staff continue to be amazing, Club level continues to be well worth the money.
One improvement since our last review was better enforcement at the pool. Staff were actively ensuring the maximum capacity was not exceeded and keeping the parents (thus children) in check.
Tips
When staying at any hotel New Years Eve, bring some ear plugs!
Lastly, the hors d'oeuvres in the Club Lounge are just that. They're for everyone and not supposed to be a main entree that's piled high.

My family and I spent three nights as this hotel. On the first morning, we went downstairs for breakfast. There were no staff in the restaurant, but a few people eating. Our son helped himself to fruit loops and I took a croissant. We all took some orange juice. The lady serving appeared and we asked for some eggs, bacon and toast for three. When I picked up my croissant, it was so hard, if I threw it at the window the glass would have shattered. The lady returned and informed us that because we had taken some items from the buffet-style table she would have to charge us for breakfast twice, each!!! We ended up paying nearing $100.00 for a few eggs, fruit loops, toast and bacon. A totally extortionate price for what was really a rather poor meal.

Overall, the hotel was clean and comfortable. The staff were nice, but when I complained about the breakfast at checkout the woman at the desk did nothing other than state that she agreed that their breakfast was not particularly good. Another complaint, there is no milk in the rooms to use for your morning coffee, and instead you get coffee whitener, which is not very nice at all.

We stayed at the Sheraton for New Year's Eve by chance as it was the only downtown hotel that we could get at the last minute, but we are really glad we did. The hotel itself had a beautiful atmosphere, very clean and inviting. The room was clean, comfortable, and spacious with a nice harbor view. The staff during check-in and out was very friendly and efficient (no long wait despite a very busy day at the hotel). The same can be said for the room service and lounge staff. We would have liked to have spent more time at the hotel and try the fitness center/pool area and check-out some of the other amenities at the hotel, but we had plans for the evening. The location was perfect for walking down to Quidi Vidi Lake to see the fireworks and then head downtown for some dancing. The Bivver lounge had a nice, relaxing atmosphere to enjoy a few cocktails, but unfortunately we were pressed for time so, stayed for just one. The food we had for room service was really good with a nice portion size, although the desserts were quite small (not uncommon for upscale hotels). All and all, a great experience and we are already booked for two separate occassions at the club level in the near future.

The Sheraton is one of the best in St. John's. Good rooms. Decent service. Drinks at Sheraton-catered events are overpriced, and bar service is a little slow at dance-style events there, but it's still a top shelf hotel. They really should consider bringing back the older dark wood look of the lobby that was there 10 or so years ago. Great food. Great garden. Great pool.
