My renewal period is also closing in fast so I need to complete 8 hours before the end of June.
In order to renew your SEP rating after the two-year period, you either revalidate by experience (12 hours in the last year, including one with an instructor) OR revalidate by test. A lot of people tend to forget that last option.
Assuming you're proficient and current in the first place, a revalidation by test will be much, much cheaper than a revalidation by experience in your case. Sure, the examiner may cost a little more, but there is no minimum flight duration for such a revalidation test so you may well be finished in less than an hour. And you don't need to do the senseless and costly boring-holes-in-the-sky-for-eight-hours.
Having said that, have you asked yourself why you have not reached those 12 hours already spontaneously? And will your circumstances/motivation change in the next few years so that you do get to fly more? A lot of people tend to throw good money after bad, once they've had their PPL for a few years, just to stay minimally current and legal, but never get to enjoy the flying. Don't be one of those. If your motivation has gone, have the guts to admit it and simply suspend your flying for a while. It's relatively easy to pick it back up once the motivation is back, even if your license has lapsed.
