No problem, there was actually a heated discussion about it awhile back with a few people arguing that Disney would not just give you the $1500 limit with no gurantee that you will have the funds available, but the CM's assured everyone that this is how it has been done and will continue to be done! Apparantly if they run that authorization for a $1 and get an authorization number from it, they can force through any amount using that authorization code therefore guranteeing them their money and alot of hassle for you with your credit card company or bank! Also, if they can't collect, they can lock you out of your room! From what I hear though, no problems ever really arise because most people know how much money they have and are not out to scam Disney!
