To fall within the intent of the program, yes........You state "we".......what I would do is purchase on at each resort. That would avoid any strange stares you might get taking the wrong mug through the line to obtain drinks. Even if you did purchase more than one mug per resort, it is still so much cheaper than the cost per drink without a mug. I was reading the cost for room service for a can of soda...$2.50 a can.........It is up to you, of course how you feel about it. i would not feel right using the wrong mug at a resort. I am even debating whether to take my mugs back to the resort for another stay now that they have the new policy. I intend to calll and ask. Having raised my kids not to lie, cheat, or steal, I find it hard to break the rules, but that is just me. The rules on reuse seem to be a bit ambiguous still at this point however.
