I had a similar dilemma a few years ago when I found that I wasn't flyting enough to enjoy it. I have up for a while. After an eight year gap I revalidated recently. I had about 140 hours on a few types.
The requirement is to pass a skill test. The examiner has some discretion about how much they make you do and is likely to test more if you're less experienced or have lapsed longer.
I did an hour each of circuits, cross country and gh/emergencies on a Saturday.
The skill test was reasonably comprehensive on the Sunday but I passed without a problem.
I did spend a few evenings reading beforehand so I knew checks, speeds etc thoroughly before I started. I found that handling the aeroplane, landing on the numbers etc came back in the first hour but it took a two more hours to do a nice pfl and get back on top of nav.
In honesty it took another few solo flights doing circuits, gh amd short nav legs to be properly happy with myself.
I think the message is that returning to flying after a gap is not too daunting, but you will need enough refresher training and passing the test might not be all you need to do to regain proper currency.
