The 48hr gap between mating is to extend the viability time of the sperm, having only had a slip mating I would definitely go back the next day,as has already been stated a healthy dog should be able to produce good semen more than once per day but I would only allow a tie once in 24hrs.
My studs have been 200 miles away in the past and meant one or two night stay in B&B, I would hate to travel abroad for a stud but then I have never been abroad on holiday so not used to such travelling.
