We have stayed at the Doubletree Suites many times. Our teenagers always liked to be where the action is. From some rooms at the Doubletree you can see MTV from the rooms. Once my daughter when she was 13 watched the guest being interviewed on TRL from our room. I don't know about the Wellington, we were always very happy at the Doubletree and never looked for anything else.

I think Doubletree Suites is the way to go. Wellington sounds like it has a great location but thumbs down on a lot! Any other recommendations welcome.
Thanks!
