Staying at the Cosmo for 6 nights in June, will be brining about $5,000 for gambling. Booked through Southwest.com so I know I can't get anything knocked off the rooms. Is it worth calling a host ahead of time and describing my play to see if I can get anything upfront? Even one dinner would be fine. I play blackjack, at about $30/hand, about 4 hours/day. 2% edge means about $650 THEO, so, I could expect about $260 in comps back. Also, my girlfriend will be playing at the same level, will they combine our play? Thanks!
