I was considering buying enough shares to use the shareholder benefit when we go on our first trip to DLP next March and just when I started to look into it the share price went up.
if you can't afford 20 shares just now, but can afford 5 plus the 30euros joining fee for the shareholders club, then I'd do that (you can always buy more shares later to bring you up to 20 to then allow you to renew your shareholders club membership every 2 years for free).
If Disney buy out DLP as reported in the recent published article, there may not be a shareholders club in the future . But for now, I definitely think its worth having enough to join the shareholders club, at least for 2 years.
