This will be an extremely busy times so tell them to use fastpass to their advantage. They should ALWAYS have a FP in hand!! Get a park map in advance or a book or something to decide what attractions & rides are "must see or do". Then try to map it out so there is limited backtracking.
I bet they would enjoy
MVMCP.
Park by park tips:
MK - Head to the Mountains 1st (either Space Mtn, or Splash & Big Thunder). Get a FP b4 going on any ride! Then hit the other must sees & fill in btwn FP's with other choices. Don't miss Dole Whips in Adventureland. Peco's Bills in Frontierland has a great fixin's bar for burgers! Eat early or late to avoid mid day rush. Alot then depends on the gender of the kids. The Cindy Surprise Celebration show is great, but boys may be bored (can't help here since my 2 are little) and they may be bored with a lot in Fantasyland & forget Toontown unless they HAVE to see characters. If poss I would split MK to 2 days (or more since they will be there for 2 weeks) & then decide what makes most sense for them (like Fantasyland & Tomorrowland one day, and then Adventureland, Frontierland & Liberty Square a diff day). Spectro, best place is behind the castle, unless you want to wait for hours to get a great spot on Main St). Wishes, Tomorrowland area (near Plaza Pavilion & up to the castle) is good, or btwn Casey's & Plaza Ice Cream. Both spots give good sightings of Tink! Harmony Barber Shop does some cool things for kids, they can slick hair & give it a color or make a mickey head design for boys, add pixie dust for girls, etc.
EPCOT - FW. Get a FP for TT & then go right to MS. Once again get a map to decide what are must see's & again plan for the best flow with no backtracking. They will love Ice Station Cool, don't miss it. Not sure about other teenager type stuff but I'm sure if they check a book they can figure out what they will like. Spend 1 day at FW. I have heard Coral Reef is good for food. You can spend 2 days at WS but not sure if that age group will like it. Don't miss the boat rides in Mex & Norway. I think they would like all the shows (mariachis, acrobats, living statues, singers, bands, etc) so check the times schedule & try to fit them in. All the places are fun to eat, but they may want to try something you can't find at home like Morocco or Biergarten. Need to get a beavertail in Canada!! They will like Illuminations. Again, stake out a spot early, the bridge btwn Canada & France is good.
AK - Never been, but I bet that age would like FotLK & Tarzan Rocks, as well at the Dinoland stuff. Can't miss the Safari or Kali.
MGM - If they are in to thrill rides, get FP's for RnR & ToT. Don't worry about having to backtrack as MGM is small. They would like just about everything so definately plan a full day. Fantasmic will be great, they may want to do a dinner package to avoid waiting 90-120 min in advance in your seat. Prime Time Cafe is very fun (not part of dinner package, but just for a meal, maybe lunch)! Definately see Osbourne lights!
Outside the parks - may be too cold for water parks but if they get a hot day, may want to consider it since they will be there for 2 weeks. FW has nightly hayrides, campfire sing a long & movies. They sometimes show PG movies so the older kids might like it. I think you need to be a guest of a WDW resort though. They may enjoy sitting up front with the monorail pilot, just ask the CM at the monorail stops. Never been to DTD but I hear Disney Quest is fun for those ages.
Other dining notes - HDDR is very fun, they may enjoy that. Chef Mickey's is fun if they want to see characters. If they haven't booked CRT (if the kids are girls) it is too late now but ya never know! WCC at WL is very fun & WL is just a cool place to see.
I'm sure I have more ideas, but this is all I could think of! Hope this helps!
