For a jolly while away on holidays, it's not worth the effort going through the training and test. I've done a few jollys like this and decided to skip the hassle and go along with a safety pilot. Saves a lot of time and money.
But if you are at home, then it's probably not such a big deal. A few hours + test would do the trick. Having got my CPL in a Seneca, I always find going back to fly a Warrior or C172 incredibly easy (and that includes landings – usually…) principally because everything is happening at virtually half the speed I got used to.
That's not to say I would get complacent about it, got to be vigilant after all, but you've got so much more time to be vigilant
