We have a category BF Guarantee on Grand Princess July 20. We know this is in an odd spot on the ship (just above the walkway) however, we're wondering, as we look through the categories of staterooms, why CC and C are more money than our BF balcony? In one of those descriptions it says "deluxe". What does that mean?Is it bigger? We are not privacy nuts, so we'll be happy with our room, however our TA says that there is a good chance we'll be upgraded from our room because there are so few of them on the ship. Any response would be appreciated! Thanks!
