Hi Big Dave, as your son is 5, he will either go to the Samvov (sorry about spelling) or the Rila Kindergarden, where they take them for 1 hr skiing in the morning and 1 hr in the afternoon. The rest of the day they play, watch dvd's, have lunch etc. The rep will tell you the procedure on the bus. Have a good one!!!!
P.S. Some find the kindergarden a long day, so you can take him out for part of the day! Hope this helps.
