Was at the Sheraton on the Park last weekend. Agree that the lounge has definitely "changed" but it's not all bad. I do find the new decor less welcoming and I have no idea why the cruved window seats all face away from the incredible views out the windows!
Drinks on Saturday night and Breakfast on Sunday were both "zoos" as others have reported. Club access is being upsold for all room types and it appears many are taking this option. Honestly, we, and several others could not even get a seat at 9:30am for breakfast. There were already several people eating breakfast in the meeting room as well! I talked to staff about this and they said that 9:30am - 10:30am on the weekends is the crazy time that should be avoided if you want to enjoy breakfast.
The staff were absolutely fabulous as always but defintiely overworked. I guess we have been spoilt in the past with turning this club lounge into our sanctuary away from the city madness. I will add that afternoon tea is still outstanding. Wonderful array of food and much, much quieter. Our next stay we will probably sleep late, skip breakfast and head for afternoon tea instead (only an option on the weekends I realize).
So if you don't mind asian inspired grazing type snack service, waiting for your drinks and sharing with lots of others, then you will enjoy the lounge.
The view and staff are still first class and the bed back in your room well "heavenly"!
