Personally it won't affect me. I've never really understood drinking in front of my child. This is a bit different but we went to WDW before our cruise last month and it was sad to see parents lined up at the resort's bar with kids in tow sitting there all bored while their parents drank. Not much of a family vacation especially when WDW has so much to offer for the kids.
What perk do you or will you enjoy,that if charged/ taken away would upset you.? Just trying to understand your mind set (not trying to be mean or judgmental nor disrespect you). Yes Disney is for children but it is also for adults( kids at heart ) as well. If adults want to have a drink on the verandah, how does this effect you( assuming no unruly behavior).
It's not just about this policy per say,it's about the erosion of perks that make this cruise line stand out.
