Luckily dw is RN and she deals with non-compliant patients all day long only to return home to surly dh. Her dad was a dentist and she will point out anyone with a chipped tooth or misalignment. However, on vacation for a splurge, if no peanut mms, she not happy means I get fallout. I always pack one of those big bags just in case. I keep her in the 'inner circle' to sustain that I've never been invited.
So amongst our over eating on normal day, we normally go this way. DW chips and mms. DS sandwiches and fruit. DD fruit maybe a cookie. Me, sandwiches and gummies. Again, we've never had more than three on one day unless you include the bowl of fruit.
If I have it right, you have three more cruises this year so shouldn't you be arranging things rather than trolling the boards?
I did actually check Cunard and under things to pack, you pick US or Europe. Since Cunard owned by Carny it must redirect to the Carny dress code. Prices very good for those ten day trips but think this year we staycation.
