what is the 2/1 deal. i see it as empty BS. what am i missing? while on the subject of bs, what is the 2 or 3 grade upgrade. i presume it is all nonsense, but does anyone really knowaaaaaaa? i have sailed on royal carribbevn 4 times in the past 2 years. i never got any offers of upgrade. wife and i paid "full price" for the offered price on each trip. the reason we ride on RC is they pick us up within 45 min of our house.
