How should I waitlist a single day in an otherwise open week?

[MicheyMouse]

Day 1 is available. Day 2 is not available. Day 3-7 is available.

What is the safest way to waitlist with the highest possibility of being successful?

I’d book the available days and waitlist the one day, then combine when you hopefully get that last day.
