Just found it... LOL
We will not be going to town on our first 3 days!

20-Jan-11 Braemar, Thomson Dream
21-Jan-11 Braemar
26-Jan-11 Grandeur Of The Seas, 26-Jan-11 Carnival Conquest 
So the 22-24th looks like our best days to go.  This is especially good for us, since we are flying on a Tuesday.  A lot of flights are also on the weekend, so others won't be booking on thier first or last day.
