The room checks have been enforced differently, sometimes depending on the resort, but mostly depending on the individual Cast Member performing them. You can go to the front desk, ask to speak with a manager about the room checks and see if they are able to help you with trying to coordinate them with your needs.
Some guests have had success doing this and others have not.
As with any concern I'd urge you to discuss it with the Cast Members working at that location.
Sometimes they can help you. Other times it is not within their power.
If you encounter an especially helpful Cast Member anywhere on property, try to make a note of their name, the town on their name tag and the date, time and location along with a brief description of how they assisted you. Then fire off an email to guest services.

The same goes for communicating with Guest Services about a problem you are having, either with the staff or your stay. If you are still on property definitely speak in person with the staff. Follow up with email once you are home.
Doing so is a way to let Disney know what they are doing that is great or not so great. Often times these emails are shared with the CM so you have the chance to say thank you in a personal way that is greatly appreciated. If there are problems with a Cast Member your feed back is a chance for their supervisors to assist them with further training. It's definitely worth your time to provide that feedback.
To illustrate that point I'll tell you about an experience that I had when providing feedback about a Cast Member. One year I was at a meeting and a CM went out of her way to go above and beyond to provide assistance that I and other people at this meeting needed. I took the time to write to Guest Services about this CM. A year goes by and I am at the same meeting. The CM that I wrote the email about was working this event again and she recognized me! She had the chance to tell me about how happy she was to have gotten that compliment and how my email was read in front of the whole team at a meeting that her supervisors were holding. She said it made her feel really proud that a guest had taken the time to give her a compliment and that it was especially appreciated that her supervisors got to see what a great job she was doing.
So taking the time to provide feedback is a win win.
Have a great trip and good luck with the room checks. Be sure to keep all of the door locks engaged and use the "Room Occupied" door hanger when you are in the room. This will prevent staff from walking all the way into your room but some of them will still open the door as far as it will go without much advance warning. Also remember that using the phone in your room sends that call to a call center off property. Any concerns that you have will be put at the end of a long list of concerns compiled by these off site operators. Go to the front desk to speak with CM's about problems at your resort. They are in the best position to help you promptly if they can.
You probably know all that but I thought I would mention it for the folks that haven't heard that information yet.
