I know I have to call to book a reservation using transferred points, but once that reservation is made, will I be able to modify it (change dates) ONLINE??
I don't know for sure, but since transferred points retain their home resort and UY and don't even show up in your DVC account I would think you can not. Good luck even on the phone you may have problems.
I dont think so because i had purchased one time use points with the understanding that i would be able to modify the reservation they were in (according to the 1st person i spoke to about this). When i called back to purchase them the next day i asked again to verify (after the sale went thru) and that member services person told me no...i would not be able to use them in a reservation modification online because OTU and transferred points dont show up online a d can only be used by calling in. I explained the person the day before told me it was possible and this person told me they knew for sure it was not because they had just dealt with a situation the other day. I explained I bought the points based on the information I got the day before so they return them for me.
I would call but my guess is no unfortunately!
No. You must call to do anything with transferred points (unless they are an exact match for your use year & resort). That includes using them for another reservation after the one that used them originally was cancelled.
