Advice on booking massages on Wish?

[Angeliki19]

Hi! Our booking window opens Saturday (we are silver level- this is our second DCL cruise) and I would like to book a couples massage. We are only on a 3-day so it doesn’t leave much time.. planning for Nassau day as we don’t plan to leave the ship. I see that I can make the reservation as early as midnight.. is that necessary? I have no idea how hard these things are to book compared to WDW stuff lol. Also, just curious if anyone has any other Senses spa advice. Thanks!
