Priority boarding protocal

[regnig]

Sailing in March leaving from Ft. Lauderdale. I'm traveling with my daughter in the same stateroom and a very good friend in the stateroom next to ours. I am 4 Star and know I and my daughter will have priority boarding passes.  Can my good friend who is a 3 Star accompany us and board as priority?  Or, should I and my daughter will just hang back and board when she does? 

TIA

Officially not, but sometimes it is not enforced at some embarkations.  In addition, you will (likely) have a different check-in line for 4 and 5-stars and suites, that your friend will not be able to use.  Of course, you can also use the general check-in line if you wish.
