You can add your name by calling and also you can add a guest.
You can add a name as well by calling into the hotel directly
As long as you have the confirmation number you can get it changed when check-in.
You can definitely change it when you get there otherwise call them directly and ask for the hotel front desk department
Do it when u get their at front desk but as long as u have a reservation under your first and its correct that all that matters because they could fix it at the front desk.... No worries my friend 😀
You should try contacting the Wynn directly. This is Google and they wont be able to change it.
You might want to call them in person, see if they could change it for you
