I don't have any advice for the OP, but I find it interesting that a number of posters have responded "rules are rules". Anybody who runs a business or deals with businesses knows that all rules are bendable. Checkout time may be 11:00 -- a rule -- but you can certainly ask for later. Would doing that make you think you are "special"? The rule is "no saving deck chairs". Will you be thrown off the ship if you do? Sure you will. (eyeroll) If a steward sees a smuggled bottle of liquor on your table, will you be escorted off? It *is* aganst the rules.
So what is wrong with the OP merely asking the company for an exception? "Rules are rules" sounds trite given the known cruise companies attitude about rules.
