Be sure to pick a date to celebrate your wife's 50th b'day when you fill in the info on the Cruise Personalizer ... and not necessarily the right day. I'd recommend the earliest date (2nd night of the cruise) cuz you'll get balloons and a sign on your cabin door for the rest of the cruise.
I'll be on the Star in April - also celebrating my b'day, but this will be my 24th cruise with Princess. Never sailed on the Star or her sister ships (Golden and Grand) but love them all.
I'd also recommend the steak house restaurant - Crown Grill.
Will you be on the April 3 cruise ... with me???
