I'm with Air Transat. Not so much worried about my dress, just trying to balance luggage weights and figure out what I am taking on board versus checking.. fun stuff.
To be honest, I already weighed what my tumblers are with goodies inside, then times it by 48 and they can all go in one suitcase and only hit 25lbs! ha!
For me it will be carry on that will be hard to meet regulations. I may have to ask around and see if any of our guests aren't using one so we can have theirs! I am not worried about checked bags as we get 6 included, then extra is $25 which isn't that hard to swallow.
