We hope they reconsider by the time TUT arrives.
We hate lugging formal wear around. We usually do USA East coast stopovers in route to Med cruises as well as post cruise stays, often using intra-European airlines and have been affected by the weight restriction fees (as well as the added agrivation getting to and from the airports and hotels)
It is a pain for us so we're definitely in the "no more formal nights" camp.
