New (sort of) cruisers!

[Cruise7654]

I haven’t cruised in about 15 years and only on Royal Caribbean. Just found out my son and some friends are heading out on the Magnifica soon. I think a 4 nights cruise. And I don’t think any of them know what they are doing. Though one is a seasoned traveler 
 

I’m assuming since they were able to book that they are allowed to cruise being under 25 (they’re all 22-23). I seem to think that was a minimum age previously. 
 

How are tips done? I know we’ve always added them at the end of the cruise but I believe some are prepaid now? These can go on credit cards yes? Or will they need cash? I totally can’t remember how this was done and they may not have good access to cash.
 

What about the dress code for dinners on a 4 night? Certainly there’s no formal night? I just want them to be prepared. 
 

My son knows nothing about anything as someone else planned it. I do know they all have passports at least LOL!

They will be fine..an on file CC can handle any charges..a bit of cash is nice for extra tips or the casino if that interests them..putting casinos draws on a CC on board can be dangerous for the first timer. 
 

They might not allow shorts in the main dining room at dinner, but the buffet will for sure..

As long as everyone is over 21, all is well on MSC. They are young and will have fun hopefully they have a drink package. Otherwise they might end up like a young man on Meraviglia last year who racked up a $900 final bill on a 3 day cruise.
