I was planning to be at the W Seattle from 7/2-7/4. Booked a special rate through Travelzoo a few weeks back at $139/nt. I now need one more day, so I'll be staying 7/1-7/4. Is it possible to start the stay 1 day earlier at the same $139/nt rate? Or do I need to create a new reservation for 1 night now at $259?

Thanks,
K
