you might be able to stay at OKW on WDW property for that amount - might be a little more.
you would be renting from a person - not Disney. if there is a problem if it between you and the owner.
now this is only if you arrive at OKW on Sunday - stay 12 nights or less. If you really want to go to the other parks less.
this is at $10 a point - you might pay more like $11 or $12 per point (depends upon who you rent from)
sun-thurs - 40 points so around $400
fri/sat - 40 points so around $400 (this once would be gone)
sun-thurs - 40 points so around $400
what I would do is go Sun-thurs - then leave on Fri - find a cheaper hotel near US or SW (which do you want the most) - stay for 3 days - then come back to OKW the next week starting on Monday - then either go home on Friday.
now Disney transportation will work for you until you leave on Fri - I would just get a taxi to take you to the other hotel.
you will need walking distance - from seaworld I might try HGVC. now you might have to listen to their sales pitch.

back to OKW - okay you need to rent a reservations - points won't do you any good.
read all the FAQ at the top of the page before you decide to go this route. If you do you need to find an owner this month - so they can make the reservations for you next month. too many people though they could wait for January and are very disappointed. Don't know why DVC resorts are so much more popular - okay maybe it is the cheaper point cost.
