Establishing and maintaining a house standard is as much about having each person understand what the level should be as it is how the gear is calibrated.
If the five rooms are similar in configuration, getting that part right is relatively easy. Getting operators to mix and master the same way may not be as easy.
Some visually oriented folks really don't have a good handle on audio. (and vice versa).
The results, therefore, may vary. As a starting position, perhaps someone can be designated the house audio mastering guru. He/she will travel to each suite for the final mix to make sure levels, EQ, compression and limiting are right. As the others in the suites see/hear how it's done, they may learn from your guru. As they do, they can do the mix and have him/her sign off on it.
Getting a good spot mix is not simply about keeping it loud enough, but out of the red. A good mix also means attention to EQ, compression and limiting. Do that and your spots will kick butt and please your clients.
You will need to standardize your audio monitoring systems in all rooms. Having the same system in each suite placed properly so you can hear what's going on is essential.
Don't know where you are, but I do that sort of consulting.
