I too would say try to book a couple of sigature meals as they use 2 credits and gives you some days where you dont need to book anything.
I would also say dont worry about what you use your credits on.
Some people obsess about only using their credits at Dinner as Lunch and breakfast werent the best value. some also like to order the most expensive things-just remember you end up paying more in tips this way.
Use your credits right at the start, we found if we hadnt used them right at the start then we'd have been left with loads.
I hear many say how theyd paid for the first meal as theyd figured out their credits. youll probably be fed up with food after the first week and may want to cancel something later into the holiday.
Have fun planning.x
the majority of our TS credits were for lunch - and i agree, it's a wonderful long break in the middle of the excruciatingly hot day...
i think because we did long lunches each day, we were able to stay full days in the park - something we never did in the past...
let's see... we were there 14 days and i think had 13 TS meals...(we missed our meal the first night - DS arrived late so we just had a CS meal in the pop food court before heading to MK)
day 0 - arrival - missed our ADR as DS and DDIL were delayed by several hours
day 1 (tuesday - first full day at WDW) -
lunch at yak & yeti (AK) - outstanding meal and service
