If you go back and watch Jillian's PI as her date with Reid was ending, you see her saying something about how she decided not to go to the fantasy suite, but that she and Reid were having such a good time, and they were getting along so well, and then the video breaks away from the interview, and then you HEAR, but not SEE, her say, "I hope I made the right decision". I'm pretty sure that she did not say those words in the same sentence as the first part of the interview, but that it was spliced together to make it seem like they didn't go back to the fantasy suite. What I think happened is that she said the first part, but then she said, "so I decided we'd go back to the fantasy suite to relax, but not stay all night." Then they went to the suite, and they did the hot tub and the robes.
They didn't show the scene because they didn't want to give away the depth of their relation. Pure speculation, to be sure, but I think I'm right.
