Many hotels in Vegas and Orlando require a one night deposit to hold a reservation.  Our #1 goal is to find a great, risk-free rate at a hotel within your selected cluster.  As such, we don't consider rates that are "Deposit Required" as risk free so we don't consider them when trying to find a better rate.  In the future, we hope to be able to determine whether a deposit is fully refundable and if so, allow a user to accept these rates.  Until then, we are only reviewing rates that do not require a deposit.
