Sorry, we’ve been away quite some time, but at least you have not yet left (?) for your October trip.
MSC have colour coding too?? --> YES.
Have you been on their cruises --> YES
can you get off when you want --> YES, once the ship has cleared port. They do NOT strictly enforce the colour codes. Or, you just ask for an early disembarkation, due to flights, and they’ll give it to you.
Coming in at 7am to Barcelona, Im hoping we could be off the ship by ??10am?? --> IF the ship actually docks at 0700, it’s almost 100% certain you’ll be off by 1000. They want you off quickly, so they can turn things around for the oncoming passengers,,
