I don't work for a chain any longer, but I used to work for Marriott, however I can kind of give you a rough idea as to what you may be spending. Keep in mind that if you have the Entertainment card or a Saver's Club card, USE IT!
Most chain hotels you can talk down in rates. Try it, it's like asking for something less at a yard sale. "Think....Will you take any less for this, or...I'll give you ten cents for that fifty-cent item."
Anyways...Depending on the quality you're willing to pay, perhaps 59 to 79 for a room, half that perhaps for a half-day. Some hotels will go down to 39 or 49 and if you're really lucky some dives you can get for 29. If you're looking on the upper-scale, plan on spending anywhere from 89 to 149 or 159, with really nice rooms even going up to 209 or more.
If you have AAA, use it, if you have Entertainment Card, use it...if you have Saver's Club, use it...other than that, try to haggle them down, but don't be dissapointed if you get to a popular location on a friday or saturday and they can't give you a discount, some places and discounts are available only on the hotels availabity..(meaning, how full they are.) If they are busy, expect to pay more, if they are incredibly slow, talk them down. If you have any other questions, feel free to contact me!
