We were on the Horizon in January, 2004 on an eleven day cruise. Each day, they had "tea" in the buffet restaurant area between 4 and 5 pm. The tea consisted of small sandwiches, desserts, fruit and the usual beverages. You served yourself going through the buffet line.
On one day, they had a "grand tea" in the main dining room between 4 and 5 pm. In this case, tuxedoed waitspeople, with white gloves, served tea sandwiches and tea. In addition, they wheeled around huge dessert carts with lots of vey nice desserts and fresh fruit. It is kind of neat watching someone pick up a discarded toothpick using tongs while wearing white gloves.
I was led to believe these amenities were common for all Celebrity ships. I suspect there are extra perks for suite occupants just as there are for Captain's Club members. However, the daily teas were open to all.
