I am planning a six-night stay. I have five nightly upgrade awards available from my first selection as a Titanium member. What is the best method to apply the five NUAs to the six-night stay? The only thing I can think of would be to split the booking into a five-night stay and a one-night stay, understanding that if the NUAs clear for the five-night stay I might have to switch rooms in between (or, possibly, I get lucky and they let me stay in the room for the sixth night). Is there a better strategy than this? Thanks.
