Details: Diamond member, stay is 14 nights, cash booking on Hilton site at Whistler.

Have booked a Whistler junior suite and am wondering how to best maximise any upgrade chances to a better suite? (cheeky I know…)

-Do I simply wait until I show up at check-in and hope for the best?

-Email/Fax in advance thanking them politely for considering me for any upgrade they may be able to offer for the long duration?

-Now a twist: my parents are coming for 4 days…Do I instead ask if they would consider only upgrading us for those four days to try to improve my chances? (junior suite I have booked already has a bed plus a pull out sofa bed so we can make do if needed).

-Other?

Thanks in advance, I realise it is far harder to provide an upgrade to a guest for such a long time so any comments/suggestions are greatly appreciated. ^

On the Hilton site and for the dates in question the only suite availability I find as of today above what I have booked is a far more expensive 2 room alpine suite that is normally around $ 600 / night more further reducing any chance they will want to provide an upgrade!

Nor1 upgrades no longer available it seems…(too close to start of stay maybe?)
