Recently I've been slightly paranoid about carrying large amounts of cash to the casino, especially if I'm flying to somewhere like Vegas. So, seems like obtaining casino credit and signing a marker would be a better than carrying. The only bad thing about it is-- that I can only gamble at the casino I have credit at (or can I play at a sister casino?). If I do apply for credit I plan on getting it at the casino where I play the most. How many of you guys use markers? What are the pros and cons? Any advice would be appreciated.
