What router should i buy for hotel & motel wireless internet?

Hotel & Motel is 7 floors and need authantication page uploaded so user can agree to the disclamier and then use the internet, need less expensive and with atleast 70 users can use it simuntaneously

For a 7 story hotel, you're going to need multiple Wireless Access Points. You really don't need a wireless router.

Frankly, you should contract this out to someone who can evaluate your facility and make a proper professional recommendation.

I think you would be better off contacing your provider . they would be much better at helping you because of bandwith you might use might not be right for your account.
