All credit cards used to prepay the room deposit may be charged immediately. Hilton Honors Base Points are available through the Hilton Honors program. Due to special group rates, upgrades are not available. Also, all hotel guests must provide a credit card at check-in that will be used to cover all incidental costs (currently a hold of $50 per day).
