You may as well try and go for the studio, but fair warning: previously, DVC units were very, very competitive and difficult to book. I know that they've finished a new DVC addition at DLH and that may help alleviate this a bit, but I'm not sure to what degree that has helped make booking easier.
If that doesn't work out, there are plenty of reasonable options offsite. DL onsite hotels, while nice, tend to be very expensive with minimal perks.
If you decide to extend your vacation to any part of California beyond DLR, I highly recommend a split hotel stay.
We will likely be spending a few days either before or after our DL stint exploring other parts of Southern CA.
