sorry for the slow responses. technically, this forum is for disney timeshare discussions. most of the posters here have timeshares on disney property and with our accomodations taken care of...a lot of us don't look into travel packages and such.
you may have better luck posting on the
"welcome to the DIS" forum, but i'll try to post what little i know to get you started at least.
* if disney is running a special package, that's probably a good deal for first timers. (many posters i've seen prefer the pop resort to the all-stars, BTW, if you are looking for the cheapest onsite hotel.)
*offsite hotels will be the cheapest option (if you'd like more room, there are also house rentals offsite that are reasonably priced.) you can also order tickets slightly more cheaply than wdw prices by buying ahead of time at undercovertourist.com or mapleleaftickets.com. wdw has a lot of ticket options, though, so make sure you understand what benefits you are paying for.
definitely scan through the different forums - especially
the disney trip planning forums to learn about theme park strategies and disney resorts as well as other offsite resorts in orlando.
