OK, so Vietnam it is! I got the partner onboard (after he asked a friend about Vietnam who said Danang was beautiful
)
I also secured SQ J seats from Singapore to Vietnam and back but had to swap around Hanoi and HCMC to get the flights to connect with our current SQ award seats. 26,000 VF points SIN-SGN and 38,000 VF points HAN-SIN per pax.
The flights are with SQ, so I'm hoping they will check our bags to Vietnam (and home) even though they are separate award bookings.
I wanted to stay in Hoi An, but unfortunately, there are no Accor properties there now, and I need to stay with Accor to make Platinum, so I'll make a day trip or two to Hoi An from Danang.
Someone has also recommended Bana Hills for a night, so I can easily add a night somewhere. The hotels are so reasonable I'd book there, leave for a night, and return to a current booking (probably Pullman).
I haven't booked any hotels yet, so open to any feedback or suggestions on this itinerary.
