The Executive Room is a nicely sized junior suite which was more than sufficient for me. And has better views than the Grand Suite (it's more forward towards the harbour and has less of the construction view). I believe you won't get this room as a free upgrade (without DSU) unless you are a frequent guest.
If the executive room is available for sale, I think it wouldn't hurt tell them that you'd appreciate an executive room if it's available (without mentioning a DSU). Chances are, they'd be happy to offer you one as a free Diamond upgrade.
