Can you record your own greeting on your stateroom phone (as you can in some hotels)? OR...can you leave a message for someone without actually RINGING their room? Here's why I ask.....my friend may be booking on my cruise now and I'm sure our staterooms won't be nearby or even the same deck. I'm an early riser, she's not. I'd like to be able to have my phone greeting let her know where I've started my day (deck 7 or 4 with a cup of tea, laundry room, Topsiders), so she can find me when she's up. I don't want to ring her room and wake her. Thanks!
