In years past, I have always taken cash with me to Las Vegas. However, as my gambling budget has gotten bigger and bigger, carrying that much cash (for me) is getting nerve racking. I have carried travelers checks recently, but there is always a surcharge and can still be a pain in the butt getting them and cashing them. After reading here about Lines of Credit (LOC) and taking out markers, I thought this is a great way to go and started doing some research. I wanted to confirm that the following is correct: 1. Lines of Credit are tied directly to a checking account(s). The casino does not care if I have a high net worth and great hard investments, only if I have liquid cash available for them to take. Do they even do a credit check? 2. When applying, the casino will call my bank to confirm how much cash I have in checking accounts only and how long that money has been there. Are looking for a six(?) month average. 3. Once I get a LOC, I can only use it at that casino for gambling purposes only. If I take a marker, win lots of money, I am expected to pay back my marker then and there at the table. I can keep the winnings in cash. 4. At the end of my trip, the casino will ask me to settle up. Should I bring a personal check to do this? 5. I am considering setting up a separate gambling checking account for LOC only. How much of a buffer should I have? For example, if I want a LOC of $25,000 do I need only $25,000 in my checking account? Or do I have to double it? How long does the account have to be active? Thanks for all your help in advance.
