Constraining activities to sets of rooms

[mma]

Hi,

I hope no one minds that I am posting several questions.

I have two activities that are constrained to start at the same time+day.
I also want them to be in rooms that are next to each other, and there are two possibilities for this:
Room1+Room2 OR Room3+Room4. Is there a nice way to do this?

What I have done so far is created two space constraints "activities with set of preferred rooms"
constraint1: room1+room2 (95%)
constraint2: room3+room4(95%)

I assigned BOTH constraints to BOTH activities. A small test produced what I wanted, but I have a feeling this is not the right way to do it.

I recommand to select the "largest set of activities" that should be next to each other.
Then give this activities only Room 1 and 2 with 100%.

Do the same with the second largest set of activities, just with Room 3 and 4.

If you are lucky you will already care about the most activities by that.

After doeing this you might think about your suggestion.

Scheduling will be much faster and also better (because only 100%) if you do it that way.
