Hello one more time 
Now, that many of my doubts and questions have been cleared for some of you guys, I have others
As usual, the facts of my trip that could affect your replies:
a. I am a single parent traveling with 5yrs twins (a girl and a boy)
b. We have a booked reservation in Pop Century
c. We will be staying from September 14 to 21, 2014
d. 6 days of Park Tickets have been booked
e. We have upgraded to the Standard Dining Plan (Table Service)
f. I don't speak English. (I have serious issues with fast speakers)
g. This will be the first time in Disney for my kids, second time for me, but first time staying on property.
Dining:
A couple of doubts here...
1. There is a 1 hour window for the FastPass+ however, even when I have tried very hard, I have been unable to find out if there is something like that for dining reservations. I know, we should be there before the Reserve time, but some facts could affect our arrival (rain, ride queues, transportation, etc). There is a no show charge and I would like to know how much a restaurant would wait for a party before that charge.
2. If I link my MagicBand to my credit card and we go to a "X" Table Service restaurant and happens that we order a "extra item" (additional side, souvenir cups for kids or even a beer or cocktail) how I will be charged for it? l read that at the beginning you have to say that you will pay with the Dining Plan, but obviously we will be walking a step beyond of its limits and I shall pay a difference. Two bills? I don't want to find out later that I was charged a full table service meal when I was supposed to pay with Dining Plan credits.
3. What happens if touring the Magic Kingdom I go to the Gaston's Tavern to get a Pork Shank and then take my kids to get some nuggets at Cosmic Ray's. I could need some fries and a drink from Cosmic Ray's for my shank, but should I be able to buy the kids meals and still sit inside Cosmic to eat my shank or this is prohibited? It is sad that in Pop Century menu you can find the shank with a side and not at the Gaston's Tavern.
4. Not exactly in the "dining" side, but I remember that when I went to Universal last year, each time we bought a round of beers from a beer cart or beverages location, we were provided with a receipt with suggested tipping percentages. It works like that in Disney or the tipping is not regular in carts selling alcoholic beverages. I read an interesting article days ago explaining that bartenders at Disney are supposed to be tipped. I am clear that a guy in a cart is not exactly a bartender, but I know too that she/he could deserve a tip. The thing is that the same article talked about some cast members that simply are not allowed to receive tips.
Mickey's Not So Scary:
I am planning to take the kids on September 19 (Friday) and use a Park Day Ticket to get inside the park around 3p.m. (with Fastpasses+ already chosen) I read that you are provided with a wristband if you get into the park at 4p.m., but what happens if you arrive earlier? Being enjoying the park you have to walk back to the entry to obtain the wristband? By the way, I have not purchased tickets yet, because the worries of getting tickets for a rainy and undesired night.
Pop Century Mini Fridges:
After a lot of reading, I am still unclear about this. It is possible to cool beers with those mini fridges or they are just suppose to keep perishable items in good condition? I am planning to get some groceries including bottled water and beers, but it wont be a great deal if they cannot get cold enough.
Lack of English skills:
I have noticed that human face Characters tend to establish conversations with the kids. Given that my kids know only some words in English, it wont be possible, but I don't want them to feel bad for this. Someone knows how the characters use to handle this?
We will do pretty well with non human face Characters, but I know that at some point my girl will face her favorite princesses and my boy, interesting characters. Would be nice to get suggestions here.
Honestly, this is one of our big issues, because in those interesting attractions where there are a lot of storytelling, jokes, etc, I could get some idea about what the speaker is talking about, but my kids would find the experience useless. Talk with Crush is a clear example. The show looks like fun, but only if you can understand everything.
Well, I can officially say that the next month will be our trip. Wow! Time is flying. I remember when I saw in my Disney reservation "120 days Remaining" (an eternity) and now the time to take my kids to that wonderful place is pretty close.
Thanks in advance for your kind replies and suggestions.
Kind regards,
Edgar
