Massage on HMC? When to book?

[SeaYa52]

I'm petty sure I read you can get a massage while on HMC - anyone know details - or when to book? Can I book this ahead of time ( although - teehee - I am running out of time) or do I need to book as soon as we board?

Last Aug, you could only book on the ship or just walk up appts. were accepted but I would check as soon as I got on the ship to be sure :)
