I've just read through the maximizing thread and have a question in relation to the minimum amount you need to bet / time you need to be betting before you're given any decent comping/discount.

Say, for example, you play $25 hands of blackjack for 40 hands, will that give you the same comping ability as walking up and putting $1000 in one hand, or $500 per hand for two hands?

At the start of your trip, for example, could you "invest" $300 into your holiday by making one quick bet, catching the eye of the gaming manager, and then asking about comping?
