Schematics...and all! I'm impressed (as always).
Yes, the Dolphin has two separate rooms. This is my interpretation of a genuine "suite", of any type. The Single-room configuration of the Swan is more of a "Large Studio", than a suite. I have MANY friends whom rent in large cities...and the "one-room" is always called a STUDIO! LOL.

Of course, the SWAN has the all-important "Conference" table, at which to "CONFER"! LOL. It's also suitable for "dining", if one prefers.
Disbug...(WELCOME

) I hope you have attained enough info here to make a decision. I would definitely vote for the 2-room Dolphin suite, perhaps on CL. Please, remember, none of the Jr. suites at the Dolphin have balconies. Yet, the windows are nearly to the floor, offering a spectacular view of the WORLD.
I also hold-out hope for your DH, as there are MANY who "get it" (mine included).

It may just take him a little more time. Be patient. Perhaps all the PIXIE DUST and upgrades at the Dolphin will help to change his perspective! I'm pulling for you...
TTFN...HAPPY "EARLY" MOTHER'S DAY!
