I'm looking at redeeming some VA points for 2 x SQ J awards, BNE-SIN-BKK return. Admittedly I haven't done a lot of background reading on VA/SQ redemptions (sticking predominately to QF) so sorry if these questions have been answered many times before.
If I transfer VA points to KF (1.35:1 ratio) and then book online for the 15% discount with SQ, it should cost me 252450 VA points (110000KF*0.85*1.35*2) + $1338 in taxes. If I book exactly the same flights through VA it should cost me 260000 VA points + $302.80 taxes. That's a saving of $1035.20 at a cost of 7550 points, a no-brainer as far as I'm aware.
However, booking directly with SQ (by transferring to KF) allows me to book a free stopover in SIN in one direction (definitely a plus). Also, when I run a dummy booking through VA it suggests I wouldn't be eligible for lounge access or priority check-in/boarding (see below). Surely that's not correct? Are there any other advantages/disadvantages with booking through SQ direct vs. through VA? I'm predicting things like advance seat selection, dealing with potential booking issues, etc. and I imagine booking through SQ direct would be an advantage here.

Also, the end goal is to get to KBV (Krabi) but as far as I can see I'll need to book BKK-KBV-BKK on a separate ticket (likely with PG/TG) and probably spend a night in BKK either side to allow for flight delays etc. I don't suppose there's a way to ticket BNE-SIN-BKK-KBV return all on the one award redemption?
Any advice would be much appreciated!
