Are you kidding me?
If you really can get the Hapuna for $73 a night, that's a no brainer.
The Hapuna is in a a FAR better location. Its directly on one of the two best beaches on the island and in a resort with beautiful golf courses and oceanfront tennis courts.
It's even costing less since the most people would value the cash and points at much more than $73 per night. (If you don't agree, PM me and I'll be happy to trade.)
Hapuna=$342 with tax for 4 nights.
Sheraton=$240 + 15,500 Starpoints for 4 nights.
Obviously I value my Starpoints at a higher value than that, but...
Hapuna=Crappy PL parking lot room.
Sheraton=Plat upgrade ocean-view room. (Suite?)
Is it really such a no-brainer? Is the Hapuna that much better than the Sheraton? I haven't read such great things about it either.
