We are currently booked at MB but our friends are at THotel. I received an email for an upgrade to The Hotel for $20 per night additional. My question is how far of a walk is TheHotel rooms to the MB casino. Is it inside the MB complex or do you need to walk outside to get into MB? Also if they are offering upgrades one week out should we just wait at checkin to see if we can get a free upgrade or $20 trick?? Thanks for any insights!
