Not sure if you're addressing the cost or the sleeping arrangements, but we have a similar dilemma. We're three adults going to Danang in April and I'd love to stay in the Atrium Suite, but according to reservations, the resort has no rollaways. The only rooms that may (easily) sleep more than two may be the entry-level Standard Classic Rooms with 2 queen beds or the (slightly out-of-reach) villas.

We may be resigned to staying at the Hyatt Regency instead.
