Wish someone would post the walkthrough. Absolutely 0 idea on what to do next, and I only have Cinderella and Aurora.
There is no walkthrough made for this. Some of the "unlock" actions are pretty random... pick the right sex act with the girl wearing the right outfit and you have to wear the right outfit too.
Have you talked to the girls and exhausted their conversations? Have you gone on dates with the girls yet? 3 different dates, sometimes you need to do them more than once. You'll have to do the same with Belle (who has a LOT of content that is unlocked in different ways.) You get the "date" option in the day time when you visit the girls at their castles. If you don't have that option available, then you haven't progressed enough with them at night.
You'll need to buy them some of their outfits too. You'll need to buy yours as well.
In the day time, practice drawing with Yen Sid & do your own drawings. At night do the same. I power leveled my drawing skills up to unlock all the attractions as fast as possible. Even when all attractions are done, I did a lot of drawing money. I never lacked for money to repair/upgrade the attractions. There were times that multiple attractions were down at the same time and that sucked, but eventually, I got them repairs and pixie dusted. After I had almost all of them pixie dusted, then I started with the other upgrades. I always prioritized repairs over pixie dusting/other upgrades. For upgrades, I prioritized the rides that had the highest amount of money coming in.
Once you have the magic kingdom map all done, then you will have the long grind to save up $2 million for Epcot. There's no fast way about that. The drinking game in the Villain pub can get you some nice cash, but honestly, it's not as fast as just spamming the advance time clock (especially if you have all attractions fully upgraded.)
Best advice, talk to the girls a LOT and have a lot of sex with them in every combination possible (for the most part, it doesn't matter what you wear, but in a couple of instances, it does.)
