I have two questions.

1. For old TP certs a partial cert can be refunded with some modest amount of points. For instance, a partial 1-5 night can be refunded with 45K points. Since the new certs cannot be extended, can they be returned for 45K points (NC4)?

2.Last time I wanted to use NC4 for a 5 night stay, but the M agent said she must find a 7 night period of award availability. Fortunately, I was able to make a 7 night reservation. This seems to be a very unreasonable restriction for the use of the 7 night TP. For future planning, I wonder if I can ask the old 7 night certs be changed to new 5 night certs? Most of my need is 5 or less nights. I rather pay the extra one or two nights if I need more with cash, than facing the possibility that I cannot use the TP because a consecutive 7 nights points stay is not available.
