The least expensive is 287 500 for 3 nights midweek at
Luxor with 2 tix to the
Blue Man Group and $75 resort credit. After that, there are 300K midweek NY-NY, 400K weekend NY-NY, 400K midweek MGM, $500K weekend MGM, then
Mandalay Bay midweek,
Bellagio midweek, Mandalay weekend and
Bellagio weekend. All have show tickets and some amount of resort credit.
I'm at 40k LP, level 151, and I still get the same amount of bonus per two hours, and the same amount of LP (100) per cycle. I have maybe half a billion normal chips and went down to 100m, then up to 1 b, down to 300m, up to 1b and back to where I am now. I didn't see a daily limit and made 20K LP in one go, so I suppose if your friend's luck held, 287K+ is easily attainable, once your bankroll gets into the billions. It seemed especially easy during some of the special quests, but I'm a little leery of playing during regular days, because if I lose it all, it might be difficult to get back to that level of play. The maximum 2h reward seems to be 5m or so.
Anyways, they have nothing to lose, and while the play during the quests is slow, I found the regular games quick, and as exciting as playing with fake chips gets. I suppose if they don't like it, and still come to Vegas, there are passes for Secret Reef and the like for 20K+ LPs. too, so not an entire waste of time.
