Serious now....I was on 4 or 5 cruises and could never get a decent Mudslide...Sooooooooo the next one I did take the blender and Mix and made our own. Delious!! I did think the blender was a little loud and might be disturbing some folks, so wrapped it in a towel to muffle the sound. Worked like a charm. I haven't taken it again. Kinda heavy to carry (we had it in our carry on). That was several years ago and I don't know if you would get by the inspection now.
Wine and champagne do just fine now.
