Our prep day was similar, but no role play !("Phew" icon)
We had to fill out the questionnaire and surprisingly Mark and I agreed on the same thing (hasn't happened since mind

)
We watched a video, met the organist and went through readings and mucis and hymns etc, then did another questionnaire which gets sent off and assessed.
At our private meeting, we discussed the results of this, 5 months later, and discussed the findings and how much we had changed, grown together etc.
They are good days, and if your church offers a pred day I'd say go for it!
