Default Difference between Celebrity & RCCL Diamond Club?

We have not sailed on Celebrity for a while. Now that we are Diamond level on RCCL I was wondering what the differences are between them. We are looking at taking a short Fall cruise and are looking at RCCL Navigator and Celebrity Constellation. I would appreciate any comparisons, suggestions regarding these 2 cruise lines and ships.

Thanks

You really have asked three questions --

Comparison between Diamond on RCCL and equivalent level on Celebrity

Comparison between the lines

Comparison between the ships

Let's start with Diamond vs. Elite -- if you sail on Celebrity, as Diamond member you can receive a courtesy enrollment at Elite level. You can read all about the Elite level perks on the Celebrity website. You do need to call Captain's Club ahead of your cruise and give them your C&A number to get this set up.

Thanks, I did that quite a while ago, before we became Diamond level.

Does Celebrity have a Elite Lounge for cocktail hour? What is the Persian Garden?

Thanks

No dedicated private room like Diamond Lounge. Cocktail hour from 5-7 will probably be held in Sky Lounge. Mid too many Elites, you'll get 3 drink vouchers per night.

Have you done any smaller RC ships? Constellation and Voyager are very different sizes. Connie is size equivalent to Radiance class.
