I know this is Celebrity CC. I am cruising on the Beyond in July. I am Elite + on Celebrity.
However, I think that RCI has a much better perk than what Celebrity has done to the new Happy Hour since they cut the number of nights they have HH.
Here is what RCI does as you all may be interested. If you don't drink, then it does not apply to you. Just like if you don't cruise, this does not apply to you.
The RCI Crown Lounge:
They have a good free coffee & cappuccino machine which is open from very early in the morning and all day .
There's continental style buffet breakfast, pastries, breads, ham, cheese, cereals etc.
Happy Hour, between 4-8, there's a hot and cold hor d'oeuvres buffet, but if there's a lot of Diamond and up members on board they sometimes exclude Diamond during these hours.
In the old ships where its in the Viking Crown lounge it's a nice quite place (except during HH) out of the sun to sit and watch the sea go by.
There's a concierge there to help with any problems or queries like a mini guest services.
Most people use their Diamond and up free drink vouchers so no $$ spent at most bars, lounges, MDR and Specialty Restaurants anytime during the day/night.
The ships officers often come by to chat during HH which can be interesting.
Finally as in any lounge you can meet interesting people
