We found during the summer VGF promo, we had oodles of time to see what the next promo is. Our guide locked us in and granted us 7 days to decide if we wanted to proceed ( this was like 2 days before the promo ended)What’s your timeline for adding? The current Riviera promotion ends 1/31, I believe. You could get direct points there and rescind if the new promotion is better if you purchased within 10 days of the promotion.
Your guide may not offer this 7 day grace up, but worth asking.
Also, you have 30 days to docu-sign, and then 10 days to rescind! ... so if you go this route, I'd hold off on signing - I think its a bit easer to simply not sign, than rescind.
A little off topic, but I wasn't aware of all this opportunity to span promos until last summer so I thought I'd share!
Good Luck!
