but generally avoid the topic these days
All evidence to the contrary.
Now, where did I put my All-Star Sports mug from '95? My family of five is going to stay in a single Pop Century room, and we need all the free soda we can get to keep our strength up while we pool hop to Stormalong Bay. Oh, and which Epcot-area resort should we park at for our Illuminations evening? We want to make an easy escape.
I sure hope my four-year old (our youngest!) doesn't grow any taller, or the CMs might ask me how old he is when I try to get him in without a ticket. My 10-year-old might be asked about the child ticket too, but we've been practicing her response. Does anyone think I shouldn't take her out of school for two weeks to go to WDW?
(There. Anything else I forogt?)
More seriously: the benefit of TGM to me is that it's one vetted source of information---you either believe the source (Mike) has expertise, or you don't, and if you do you can read a single viewpoint and adapt to your own needs. Ask a question on the DIS, and you'll get ten responses with 12 different opinions---with a few exceptions, (the upscale Garden Grill menu was horrible; CRT breakfast requires you to call first thing right at 90 days), there rarely are consensus opinions about *anything* to do with WDW, and I don't have time to figure out who knows what they are talking about, and who doesn't.
Of course, you could argue that, as there are dozens of ways to skin a cat, any one of those dozens of opinions would lead to a fun vacation. Heck, my brother and his family went to DL during the most crowded part of the day (afternoon) during the week between Christmas and New Years (the busiest week of the year), saw precisely three attractions, and *still* felt that they got their money's worth for the day. At some point, the decision to use or avoid morning MK EMHs during the second week of February when the moon is full isn't going to make or break your vacation.
If you think Mike might know what he's talking about, try TGM. If you decide you didn't learn enough to justify your $20, ask for your money back. My understanding is that is no problem. If you'd rather just read the DIS and learn that way, that's great too! You aren't going to ruin your vacation by not buying this guidebook or reading that DIS thread.
