The Wyndham has a Spanish fort pool area and a pirate ship pool area with a water slide and a floating river - both are beautifully landscaped with nearby pool bars/food and a walkpath circling the lake that takes you to minigolf and lots of other recreation (ping pong, pool tables, arcade games, crafts, outdoor movie nights by one of the other resort pools, outdoor stage, etc.). It's very family-friendly and your 12 year-old would likely enjoy it very much! Sorry I can't make specific comparisons with The Signia's pools since I haven't stayed there. But it is a hotel and won't offer the full extent of family-friendly activity options that a combined hotel/timeshare like the Wyndham at Bonnet Creek can offer. If just planning on a resort day/night, then I'd choose the Wyndham, simply to have some fun indoor activity options in case of a rainy day.
