Agreed, Toilet Training can be challenging enough without adding the extra pressure of being away on holidays - I doubt any of you will enjoy your break or toilet training under those circumstances.

Wait until you are home and can focus on the task. We toilet trained in a couple of days and had about 25 accidents on day one and barely any on day two. But we were home, within sprinting distance of the loo, and had no other distractions. Also, I think its confusing to put them back in nappies when its convenient for you, they then get confused about when its ok to wee on the toilet and when its not, assuming you have another 7 hr drive back the other way, you may undo any progress you do actually make while away.
