Spending Money & itinerary advice for Vegas

[excitedbunny79]

We're off to Vegas in June, we booked via BA staying at The Wynn which includes the breakfast buffet. It's a 40th Birthday blowout, so we don't want to scrimp on food and drinks, but reading it's expensive out there now (I haven't been for 10 years)

I've been playing My Vegas slots so we've got buy one get one free at the Bellagio/Mandalay Bay/Mirage buffets, but I'm not sure whether we'll be buffeted out!

I also have no idea how far the Wynn is away from all the other hotels, last time we stayed at The Bellagio so I know my bearings from there, but I don't remember seeing the Wyn at all. Would buying the monorail pass be worth it?

Any Las Vegas veterans got any advice on an itinerary as I'm a bit lost!
