Add most frequent guests/highest revenue generating guests report

Similar to the Company/Top TA producers, I would like a report that shows the most frequent (20-50?) Guests that stay with us, and the top spenders.  (Ms. Smith who stays with us 3 days a week every week at $107 might actually spend less than Mr. Jones who spends 2 Saturdays a month in a suite at rack and drops $500 at the restaurant every stay).  

This would be be invaluable in identifying who we need to be focusing on company as well as for loyalty rewards.
