Most negative reviews tend to come back to a lack of planning. Lines were too long and they never used Fast Pass. Couldn't eat "anywhere" because they didn't book ADRs. Missed X event because they didn't take into account the transportation being full at peak times. Make your ADRs at 180. Make your FP+ at 60. Read the boards, see what's changed, ask questions. You'll be fine.
I am one week away from a first time, 10 day WDW trip and I would have a very different experience if I hadn't planned.
Vida- could you let him do his own thing? Would he have a better time if he wasn't tied to the family the whole time? My teen loves his solo Disneyland time. He drifts back to us for meals but some days he needs a couple hours to single rider his favorite thing over and over. Our rule (even in CA where the parks and hotel are next to each other) has been that he may not leave the current park without telling us and we set a meet up time. He has a cellphone and it has worked well for us. Don't want to walk in the rain? Okay, stay here and we'll meet you later. Want to stand in the 45 minute line? Sure. We'll go ride something else and meet you here at our FP time. I know there's a temptation to keep the family together on a family vacation but some teens are more pleasant if you give them a little room to be alone. (Mine is now 18. His rules will be a lot looser. Once they register for the Selective Service it's hard to tell them they cannot go back to the hotel alone.)
I offered to let him do his own thing but he didn't want to. He wanted to be with us. I am not a hover mom. I have no issues letting him roam free. lol He has a cell phone and gets plenty of freedom at home and I told him before we left he could have free time. But nope....he wanted to do things with us. He wouldn't even go ride a ride alone while we sat on the bench. The only times they were ok being away from us was when we left them in the room to go to TS and Tambu Lounge. Another night we did Epcot and they stayed in the room and were fine.
The night in MK we had dinner at CM...his favorite place, his pick for the trip. He loved it and had a great time. As soon as we left I saw it was raining and he wanted us all to go back to the room and skip MK. I told him he could go back. We were on the monorail and staying at the Poly. Nope....he wanted to be with us as a family (his words). Once at MK it started POURING and he was more worried about his hair. Oh and his sneakers getting messed up.
The constant complaining is what did me in! That's what annoyed me the most and made me lose it. Every 5 minutes he was complaining about something.
Now after day 3 he shaped up. I did threaten to send him back as an unassisted minor the next day. I was about 95% serious and even called his father and his father spoke to him. My SO also spoke to him. The next day was a rest day, pool time, a nice dinner and the next 7 days went much smoother. Maybe he was on overload and overly tired and that rest day helped him a lot.
ETA: Travel day was a 12 hour flight delay due to mechanical error. It was a very long day and not a nice way to start our trip. The next two days were rope drop days. So he may have just been irritable and cranky and tired. But again...he was offered to sleep in and not do RD but he insisted on going with us.
I have read and heard SO many negatives recently from people on review pages/friends/etc!
