I agree with Sailinglisa:
We very much enjoy a drink on the veranda before going to dinner - and perhaps a nightcap before retiring for the night. Thus, we will bring alcohol onboard for that purpose - unless someone stops us at boarding time.
We will order wine during dinner and perhaps a mixed drink or two while relaxing by the pool.
We rarely sit in a bar and drink anything but sodas.
Doesn't matter to us what the alcohol policy is. If cruise line is serious about no alcohol being brought onboard - we will abide by the policy and it would not change our future cruising plans as regards that line.
Smilin' now... 'cause Pooh is Mardi Gras Bound
Laissez les bon temps rouler!
