I was a Newbie 2 weeks ago as well. There are pros and cons to staying there that you need to weigh.
1. For booking, you can use eBay or some of the other rental places. Many people have points they are trying to use or run it as a business. redweek.com, eBay, Ken Price as mentioned previously, vrbo.com.
2. Pros: You get a much bigger room for the price. WBC has plenty of activities and amenities that are not at DW resorts. The money saved staying here is king. DHS and Epcot are 5 minutes away. AK and MK are only about 10 minutes. All of which are faster to drive to than Disney buses. You can view MK and Epcot fireworks if you are in the right rooms in the right tower.
3. Cons: I think you need to have your own vehicle. This also brings in the $18 per day parking fee at DW unless you are an AP holder. You miss out on EMH, but I didn't miss those any way. You do not have that Disney vibe there. That is not a big deal because less than 5 minutes away you can go to Boardwalk to get as much as you want if you choose.
