Salon Service - Which nights are normally formal nights on Carnival Glory?

Hi there, This is my 1st cruise on the Carnival Glory and I am trying to schedule an appointment to have my hair done on one of the formal nights before there are no appts available but I cannot find anywhere that it tells you which nights are formal night. Does anyone know?

Normally sea days. However, not the last night.

Glory 7 day cruises is second night of cruise and 6th night. Since Glory goes Saturday to Saturday sailings round the clock this is Sunday nights and Thursday nights.

On her now. It’s Sunday and Thursday.

Book early, they fill up. Most ships have only 2-3 hair stylists.

Thank you all!:)
