My MIL is a 'pip' too. When ever we go, she downplays it likes it's no big deal. She always asks if we're going to Universal too. She says she likes it better, yet she doesn't go on any rides.
But when she took her DD and family it was the best place in the world! Funny though, she's never asked to take my family.
She doesn't get why we go to WDW but she and FIL go to Aruba every year. They stay at the same hotel and eat at the same restaurants every time.
