Hello, I haven't stayed at Orange Lake yet... We have it booked for our next trip thru my inlaws timeshare week!
When you book thru RCI, you actually book a specific section.. not just any unit in Orange Lake. So, you can book either West, East, North, or the new River Island (which is probably the hardest to find any availability)
I have done a lot of reading and research...
The units at the West section have all now been completely renovated!

There is one building at West which has (I believe) Studios and two bedroom units... (probably create three bedroom unit when combined???) It is unclear whether all renovations are complete in this one main building. All the individual villas are now done. Most of the units in the building seem to be completed from what I hear... But, generally, from what I have read, I would still NOT recommend this building, the Clubhouse Building, at the West section.
Our reservation is for the North section... The units there are two story, and not the bigger buildings. It should be one of the quieter sections, and this helped us to decide on North! the East section is larger six story buildings... And the new River Island section is small highrise buildings.
Of course you should go to the Orange Lake website... just do a quick search on Orange Lake Resort and that will pull it up for you.
Also, for a TON of information and traveler photos, go to tripadvisor (oooops edited to correct, I had accidentally typed in travelocity) and just type in Orange Lake Resort. Once you click to pull up Orange Lake Orlando, just click <more> to expand the user reviews... When you do this, you will see that a section for Traveler Photos pops up with Hotel Photos on the top of the page... You will find a ton of photos there!
Orange Lake has to be the biggest resort... Therefore it has SO much to offer. The new River Island waterpark style area with lazy river, two slides, a zero entry pool at each end, restaurants, bars, occasional weekly entertainment, etc.. sounds impressive.
Hope this helps!
