I maintain that if Disney wants me to buy a new mug every trip they need to have a new mug for me to buy! how many years has the current mug been around? For the last 3 years we have been going at least 3 times per year. That's a lot of the same mugs for us to buy!! I'd say it's not worth it for me to buy the mug every time because as someone else stated we don't spend that much time at the resort during most trips. When they actually made the resort mugs we were excited to buy a new resort mug, now that it's been the same design for at least 2 years we have no interest in them anymore. Also, as @
Cmdr_Crimson stated the $5 mugs in the parks are cooler.
