I would say you are safe booking it all at once. We are BCV studio reservers as welland have never had a problem (in the 11 month window) with late January, first week of May, last week of October, and first week of December. Whih reminds me, I need to book our 12/3/05 trip next week! January, with the exception of the MLK holiday is generally a "slow" time of year.
