We like to stay at the Imperial Palace...NOT fancy but hey, how much time do I spend in my room anyway? It's like $79 a night Sun-Thurs and it's right in the middle of everything! They have $3 blackjack tables too (the only ones we could find ON the strip) and the waitresses were pretty quick to bring drinks.
I love the buffet at the Paris. TIP: find out when breakfast changes over to lunch. Get there right before that and pay the lower priced breakfast price and get to eat lunch
Ask for comps if you are playing at one place awhile. I usually sit the same table for hours placing small bets. Bet bigger when the pit boss is looking

After 2 hours or so I usually ask for a free lunch or BOGO lunch. After 5-6 hours I usually get compted a free show ticket and/or dinners...depending on what resort. Don't forget to use your casino card and give it to the dealer when you get there to rack up points (or whatever that resort uses).
