How comfortable do you want to be? A few years ago...you could stay at the Comfort Inn on Palm Parkway for $35/night...BUT you had to share the room with cockroaches. With that said, I like Palm Parkway the best of any off property hotels because you just cross the road to get onto Disney property.
Here are some tips:
Go in off season
Look in discount books, budget boards, priceline, etc.
IF staying on property...GET AN ANNUAL PASS!
We've stayed on property in a value for about $75/night.
DO Keep in mind that without an AP, parking for off-property guests is $14/day.
Matter of fact...even if you stay off property... GET AN ANNUAL PASS!
IF you have enough time, I wonder how well you would work out in purchasing a DVC contract and using multiple year points. If this is a one time thing, sell. Purchase RESELL. Its not likely, but you could actually come out ahead doing something like that.
If you fly into Orlando, look at the fly/hotel combination packages on travelocity and the like.
Looking forward to comments.
