Thanks all for the replies. USCG Teacher and RoyalMoyal, thank you for the resources. SpaceNoodles you are absolutely right, they are clearly on the deckplan on the web page. Except I was looking at the deckplan you get when picking a cabin for booking, which does not include the tick marks. Then I used a couple other resources I have used for years and they didn't have the checkmarks either. I just double checked and sure enough, the ticks are on the deck plan when you go through the RCL main page, but if you go to book a cruise the tick marks are not there. Odd that they don't use the same deck plans. But if had searched better I would have found it. *facepalm*
Thank you again.
