Jonathan,
It's great this field trip works out for your schedule. I would add that there are many positive merits to good field trips, whether they fit the schedule or not. In fact, in most instances, a field trip will by necessity break up the regular schedue of classes. Not least among benefits is the rejuventation and motivation many students receive after being inspired by what the see, hear, and plan in their mind for themselves in better future ahead.
