We stayed at Sierra Suites LBV in Dec 02 and were very pleased with it. Our room was squeaky clean and their staff is very pleasant.
We didn't use the shuttle, so I can't comment on that. The pool was clean, but very basic (no slide, waterfall, etc.) The breakfast is continental -- bagels, muffins, cereal, etc.
I also looked at Radisson Resort Parkway, but picked SS for this trip because I preferred the convenience of having a kitchen, also, I knew it was likely to be cold during our visit, so I wasn't sure how much time we would spend in the pool.
I think both these hotels are so nice that you can't go wrong either way. Good luck!
