The price could be substantially cheaper than what you initially saw. This happens because booking websites often employ dynamic pricing strategies, adjusting rates when they detect you're keen on a particular property.

Regarding when to travel, Sunday through Thursday generally works out more affordable as you avoid the weekend price spike.
