Does Booking in Advance Save Money?  A little.

Below is a graph tracking the room price for a weekend (Friday + Saturday + Resort Fees + Taxes) in July.  Prices were checked daily for 41 days.  You can see some slight spikes in prices that settle the first few days after.  There’s definitely an upward trend but at the end of the day the biggest swing is about $100 for the weekend, not much to lose sleep over.
