Friday and Saturday nights - especially at the front of your trip - are the ideal times to visit all those resorts you miss. The CR, the Poly, the GF, AKL. Even the Y&BC for SAB (assuming you aren't staying at BCVs). Or, saving alittle money, the moderates (I know there are a ton of POR fans who would stay there even if it wasn't about saving money). Or a Universal hotel and get FOTL at Universal if you are going there anyway.
For the frugal, getting an offsite hotel can't be beat - especially if you aren't bothering with parks the first night. We have usually flown on Saturday and I've learned I'm too tired on Saturday for big plans - so dinner and a hotel pool work fine.
