I am Diamond level and would choose Signia over Waldorf every time !
It is impossible to get reservations and even more impossible to use HHPoints .
If you find availability grab it and continue to look around .
But you should keep Signia.
I have posted many times about the amenities .
Don’t forget to verify the cancel policy…
Disney has 8 day cancel policy now!

I have had to use my points at the Waldorf when I really wanted Signia
Hilton seems to restrict points at Signia .
