Before buying our contract, we rented points for a standard view studio. They are found in both Jambo (the cash hotel) and at Kidani (the DVC resort). You can search and find dozens of threads here to explain all the differences between Jambo and Kidani.
In my opinion, Jambo tends to be "busier" in places like the lobby area than Kidani due to the hotel aspect. Both are great.
Bus time isn't bad but can take 15-20 minutes to MK (once you are on the bus). For some this is too long a ride. For others (like us, we dont mind at all) this is not an issue. This seems to be a topic that is very important to some vacationers. If you aren't comfortable with waiting for and riding the bus system to the MK area then an MK/Epcot area resort may be a better fit for you. If you just miss a bus and have the entire wait plus the ride the commute can be upwards of 35-45 minutes (worst case). For some this is a deal breaker. For others it is a chance to meet new people waiting/riding next to you.
If it helps any, we recommend renting points first to see if it is for you. We are glad we did. We did end up buying into DVC when we were ready to.
