We just got back from the 9 day San Diego round trip cruise (December 29th to January 7th).
Yes, in our cabin there were two umbrellas, and binoculars.
Great cruise. My only gripe: my wife likes to order a 'dirty martini' with olives. The bars simply dump the olives in the glass: no toothpick. If you ask for a toothpick to hold the olives, they will stick a piece of skinny pasta into the olives. Which soon deteriorate.
Moral: take your own cocktail picks with you. My wife vows she will do so in future.
