Having just returned two weeks ago from Disney, here's my opinion. Of course, it's not worth much. 
On the up side, liked it for opening our room door, for making purchases but could they have not put those keys a little farther apart, using it photopasss and having them scan the magicband.
On the down side, three fp+ a day is not near enough for our family. While this trip was a Girls Trip and we didn't do the coasters our family of adult boys will be less than thrilled. We have a family trip for Thanksgiving and I'm definitely concerned. We have always used fastpass to the fullest and 3 a day is not it. Tiered fastpass is also something I'm not fond of. Actually it stinks. We will be standing in line alot more I'm sure and I realize it will be crazy busy. I wish we could go at a different time but we still have a son in high school. I'm a planner and I love planning our Disney trips but planning your fp before your trip just isn't something that trips my trigger. I realize things change. It has. And I don't like it. Sorry fp lovers.
I realize fp+ is still in testing stage but if something is going to change, can't they just do it now. I'm not a patient person.
These are just my opinions. We live in a world where we all have different ones for which I'm happy.
Happy Disney Planning Everyone!!!!!!
