Go around the side of the Discovery Center in JP. If you're coming in through Lost Continent, it will be a pathway to the left, just past the Watering Hole. This little nook, imo, is the most serene area of IOA. It gives you a phenomenal view of the Hulk, Doom, Dragons, etc. The foliage around the area is beautiful and is a great place to hide out and relax for a few mins.
In USF, there are a few nooks/viewing areas along the lagoon which offer peaceful seclusion. One is by the old Herc & Xena building. The other is near Cafe Labamba.
IMO, those spots are great to just hold your SO and take a peaceful view of the park. You can be all

as well.
