OK. Sounds like you want passes for about 6 days. I wouldn't recommend the UPH because you'll end up paying for days (and probably features) you won't use.
Here are a few options to consider:
6 Day Park Hopper Plus - Gives you 6 days to hop between the 4 main theme parks and two PLUS options. Each plus option is good for one VISIT (note visit, not day) to a water park or Pleasure Island.
This ticket will cost you about $300 per adult if you purchase before arriving at Disney.
You could also consider a 5 Day Park Hopper Plus. You indicated that you have 6 days on which you want to use the theme parks. With a 5 Day PHP, you would get 5 days at the four main theme parks and ONE visit to a PLUS park. With this ticket, you could visit MK, EP, AK and MGM on 5 days, and then on the 6th day just go to either Blizzard Beach or Typhoon Lagoon.
The 5 Day PHP is about $270.
Finally, not to confuse you, but you could also consider an Annual Pass. The AP will give you unlimited admission for a full year. So, if there's any chance of you taking another week long trip by November '05, you can actually get two (or more) trips under the same pass.
The standard Annual Pass just gives you admission to the four main parks. It costs about $403 for the full year.
The Premium Annual Pass gives you unlimited admission to the four main parks, the water parks, PI and DisneyQuest. The PAP price jumps up to $531.
Still with me?
With regard to putting park passes on your room key--it can be done, but it will cost you. Disney now has a two-tiered pricing scheme. If you buy your pass at the resort, they CAN put it on your room key, but it will cost you about $25 more PER TICKET than buying your passes in advance. You can buy Hopper passes in advance from the
Disney Store, Disney.com, or even a lot of reputable third-party Internet vendors like Ticketmania.com.
If you decide to go the Annual Pass route, disregard eveything in the paragraph above. APs cannot be purchased in advance, you can only get them at WDW, there is only one fixed price, and the AP cannot be attached to your room key.
Really, if you're a
DVC member and plan to be back in the next year, the AP is probably the way to go. In fact, if you were to buy the AP, you could still pop into the parks on your arrival day and the day of the Petty Experience, and it won't cost you anything extra. APs truly give you the ability to come and go as you please without worrying about getting your money's worth each time you set foot in the park.
