A couple of times I have checked my mlife offers and noticed that I am able to get a better offer than I have already booked. I ring them and get this changed over and its not a problem (I ring up because they always seem to be able to wave the resort fee on the phone, but it would charge me if I booked the offer online). What i am asking is, is it frowned upon to keep cancelling reservations and rebooking new offers? Bearing in mind that it is MGM who keep dangling a different carrot in front of me. Would any of you feel uncomfortable cancelling and rebooking 4,5 of 6 times for a trip.
