I always enjoy the debate that ensues when Concierge is mentioned in a post!
To try to answer the OP questions, I just traveled over NYE with 7 family members. Four of us were in a 1 BR suite, the other 4 in an inside cabin (due to SIL's multiple phobias, I just cut out the veranda option). Interestingly, my DN felt sorry for us b/c we didn't have a porthole! Love kids...
Anyhoo...
While I wasn't able to link their excursions or meals on line, I wouldn't be surprised if, had I asked, shoreside concierge would have done this. This was clearly my experience, perhaps others are more facile with
DCL's at times quirky system. The only thing I'd asked shoreside concierge (other than dinner reservations) was for tickets to the princess meet and greet (I didn't know if my mother would have to have her own to go with DN, she didn't, fyi, one ticket per family, however that is defined). As it happened, when we had our meet and greet with Ashley, he had tickets for both my room and DB/DSIL/DD/DN as well as UNASKED for tickets to Anna/Elsa. Again, I hadn't requested tickets for the other room, they were provided.
We didn't order from the menu so I can't say, although normally I don't think they keep a firm tally of what's ordered. I will say if there are just a a small group in the Suite and then there is a large order, someone might notice...do anything...maybe not...but possibly notice.
On a different note, for those of us who ask "how would they know if you're in concierge?." Well, many wear their KTTW cards on lanyards. Concierge is gold, non is silver (an exception, I believe, is EDGE for the tweens which was red when DD attended). Now, not everyone wears theirs (I usually have mine in my pocket or forget it somewhere inconvenient). That leads me to the second point which is the Concierge Hosts know the guests on their floors. I'm pretty sure there is some sort of horrible photo from boarding that is sent up and I wouldn't be surprised if any history accompanies this. How do I know? On our most recent cruise my DD (age 15) was allowed to board with us (who were in the suite) so she didn't have to sit in the terminal for 2 hours waiting on the other family members in her 9th floor room to arrive (and why they weren't there when we were...long story with family dynamics. Short answer-maintain the peace, folks, gotta maintain the peace during a multi-generation magical family cruise. Sigh).
The Host remembered her-asked her why she wasn't on the CL with us (death glare from 15 y/old) and gave her tickets marked CLEARLY with her room number 9---. She also threw a ROYAL HISSY as only 15 year old girls can when I told her that the CL was off limits to her. Because I'm one of those rule followers.
My family did visit us in our room, but DN preferred her "porthole" room so DMother spent more time there. DD was swanning all over the place (but not the CL!) and I think we maintained a nice balance between meeting in public places, cramming in their room (I'm claustrophobic) and spending time in our larger digs (I was sick [but not contagious-migraine} the entire cruise so fortunately I was particularly fond of my room :I ).
I do believe the Concierge Hosts try very very hard to make everyone happy. Even not feeling well, I could appreciate how hard they worked.
