Good question. Both CN and CTI have a Deluxe Ocean, and CSS has a Deluxe Ocean Suite and a Deluxe Ocean Verandah. Only CSA has nothing called Deluxe.
We had a Deluxe Ocean at CTI. There wasn't really a sitting area. There was a chair in the corner and another at the desk. But there's a couple of chairs out on the balcony. We were in building 4, but this category is also in building 1.
We had a Deluxe Ocean Verandah at CSS. Again, no sitting area except out on the balcony. I think that category is all over the place, but we were top floor of G block.
We didn't care about not having an indoor sitting area. When we wanted to sit in our room we preferred the balcony anyway. Are you maybe thinking of a 1 bedroom or a suite that having sitting areas?
