We always stay offsite on our Saturday travel/arrival day. This is just me, but it bothers me to "waste" points (or cash) on a resort day when I won't be rested and relaxed from travel an ready to enjoy every minute (we always check in around 8am and use our KTTW and resort ameneties until our room is ready).
Typically, I'll either go the cheap route and Priceline a 3.5 star in Disney or Universal (max. bid 45$) areas OR I'll go for a 4-5 star resort (max bid 65$).
For the 3.5 stars, we've gotten the Universal Wyndham and Celebration-area Radisson - both were very nice with large, well-equipped rooms and both had great food-court areas (the Wyndham had a Starbucks and Ice Cream Parlor)
For the resorts, we got the DTD Hilton (which gives you extra magic hours). It was really nice - we loved being literally across the street from DTD, and at Christmas they had Santa there (there's also character dining and a Benihana) and the Peabody (which my kids claim is the best hotel they've ever stayed in - rating it even higher than the Ritz - all because the bathroom had its own flat screen TV)
I've also done the Swan w/ the teacher rate.

We're staying at the Dolphin for my birthday weekend Food & Wine/
MNSSHP - with the teacher rate and the birthday deal, we'll get 3 nights in an upgraded balcony room for 480.00 total.

Shop around - there are lots of GREAT places to stay in Orlando and lots of GREAT deals.
