Hi there we stayed in his room one night until our upgrade was available. The room has a king sized bed, dresser, walk in closet, smaller washroom and a terrace facing the garden. There is a flat screen tv and an iPod docking station. The only thing that made this category different (actually 2 thing) were the view and the smaller washroom. If those things don't matter to you then u should be perfectly happy with this category.
We stayed in an Ocean Jr. Suite at CTI and I believe the only difference between it and the Garden Jr. Suite is the view. Our room looked out over the water and Tower Island and the Garden Jr. Suite looks out into the garden area. The rooms are large and the bathrooms just as large with a separate jacuzzi tub and shower. There was plenty of drawer and closet space and a comfortable sitting area. I'd be happy to answer any other questions.
We also had an Ocean Jr. Suite at CTI recently. We actually requested a room change from Block 2, and were given a room in Block 3. What a difference! Be sure to request something in Block 3 if it's available -- you'll be right above the lobby and central to everything on the resort, with an amazing view of Tower Isle! (assuming you get an ocean view room and not a garden view room).
