do you think its worth it for one trip? or does it take a few trips to make the money back?
you need to work it out really - Salon Mickey is free for shareholders and their families, every morning, up to 5 times per month (so free hot drinks and pastries).
15% off at table and buffet service restaurants in the resort
15% off your souvenir shopping at the resort
10% off all your shopping at Disney Stores in the UK
10% off at Earl of Sandwich in the Disney Village
15% off any annual passes you buy at DLP (not so great an offer at the moment because other agents have the annual passes cheaper).
plus occasionally shareholders get good exclusive offers, like the Spring offer ust gone of a free VIP fastpass for up to 4 guests (usually these cost 60 euros per person).
As above, 20 shares for free entry to the shareholders club costs around £100 just now.
So work out how much you're likely to spend in one trip on food and souvenirs, consider whether you'd stop for a mid-morning break of coffee etc (free at Salon Mickey) and see whether its worth the money for you
