"a clamp-on beach chair umbrella to use on the Dolphin cabin balconies?"
And it appears you got "bumped up" from ??? to a mini suit...what did you start with to get that?
So sudddenly from "never had an open balcony" your now in a mini suite on upgrade, yea right
, unless you paid for it, did you? If not,,its hens teeth for that sort of upgrade...
Nice if you did, and you dont have to pack an umbrella, for one in the breeze of the ship moving at 22 knots, it will be "sucked" overboard, including what you clamp it to.
There is no balcony on a ship that has direct sun all day, in fact they are mostly in some sort of shadow. So its not a concern.
Sceptical, but enjoy your upgrade
