Babs, I agree with Marc, Kathy, and Cyndi, go ahead and book when you can (as early as possible), and if a special becomes available then you may get a pleasant surprise down the road. This happened to us, as we booked over 1 year in advance, and then about 60 days prior to our cruise on the PG, RSSC ran a special that was a better deal than what I had originally booked. They cheerfully credited the difference back to me with no issues.
Cheers,
Ken
