We booked once we got here. We did need to be a little flexible with times and days, but we booked early in our week so we could plan our other days' activities. I'm sure they could do a mother/ daughter treatment. We did the whole family in one room. They normally do not allow children in the spa, but with the parent they make an exception. However, we did our treatment, then left the spa area. We did not bring the kids into the facility to use the hydrotherapy, steam, etc. Instead, I used it before our treatment, and my husband used it after.
