Resort Level 5

So I'm having a really hard time getting my resort to level 5. I'm currently sitting on 4 1/2 stars. I've got my tower fully upgraded, I've got several rooms equipped with TVs and game systems, a good sized pool, pool bar, slide, hot tub, 2 bars in lounges (one has a bowling alley, skeet ball, basketball, bubble bar, DJ Booth, and dance floors). I have spa services toggled on, room service toggled on, 8 food buffets, 2 fire walks, and the price is cheap. I'm really not sure what else to do.
