On our Emerald cruise 2 weeks (also our third trip) ago we didn't even notify them of a birthday & out cabin steward happened to see a birthday card hanging from our mirror & set out balloons without asked. They also sang happy birthday in Sabatini's with just a simple notification upon entering. We saw so much of our cabin steward I wish he would have gotten lost for a while each day and were constantly making him move in the hallway.
Anytime dining couldn't have been better or faster if we had asked for it.
Captains circle invitations showed up right on schedule. After 15 cruises on Princess you should just about know which night to expect the party. Although there might be more than one party, you can choose which you'd like to go to or do all three if you like.
Drink servers will tailor any drink to you taste - even one that doesn't taste quite right. Our waiter in the Explorers lounge one evening didn't hesitate to fix my wife's drink- all you have to do is ask.
I don't expect the Grand to be any different.
