I concur man. I'm not going to claim to be an expert on My Magic+ or the MagicBands but I see it like this, Disney is simply getting with the times & using their resources to ensure we're able to have fun despite their parks being crowded. We live in a very fast paced world now with the internet, smartphones, tablets, etc so Disney had to provide services that will keep up with all that.
Yeah it may hinder some of the spontaneity that we've grown accustomed to when we were kids. But some people fail to realize that when most of us were little kids, there was only Magic Kingdom & EPCOT and not as many Disney resorts. So at that time, spontaneity was so easy to do because there wasn't as much stuff to do & the resources weren't available as today. So me personally,
I will never ever ever complain about my Magic+ unless their systems acts stupid which happens sometimes. LOL. I LOVE MagicBands, I've collected a lot of the Limited Edition ones and love the various ways they can be used. FastPass + is great for the most part, it has its drawbacks as far as availability but its great nonetheless. I don't understand why a lot of people complain about not wanting to plan months in advance when all vacations need to be planned months even years in advance anyway, its just that the planning methods may be different.
The point of going to Disney World is to experience the magic as much as you can in the amount of time you're there. With crowds being what they are, it would be insane to skip making a Dining ressie when chances are that certain restaurant will be packed. Or skip making a FP when all the popular rides have minimum wait times of 45 mins average.
Point blank, instead of complaining about the planning, I feel that the complainers should simply find a way to make the planning fun, go to Disney World & do exactly that.....have fun. LOL.
