Hi! We just got back and used Connections vouchers at the Mara (AKL)... and honestly, it just depends on the person at the register.
I had read many times on these boards to just take the approach of saying to the waitress/waiter 'this is my 1st time using these... what can I get?" - you will find different things at different times.
Example: 1st day we used voucher at the Mara - we were not able to get the large pizza, but our friends DID (they went through a different register)!
At Tangerine Cafe in Morrocco (Epcot World Showcase) - 3 of the 4 times we used it there my DH was able to get any of their desserts (he likes the 'mousse cake') and they offered us an extra side (even though the platter we ordered comes with 3 sides of it's own)... but the last time

not only was she a bit rude with us, but no extra side (not a big deal) and ONLY dessert option was the BAKLAVA. Oh well.
At Beaches & Cream we had to question a bit to get a shake as a drink the 2nd time (my DH wanted the sundae all to himself) (
and PS We were NOT ordering the Kitchen Sink) and at the Pepper Market I had been able to get a Mocha coffee as my drink and a small salad as a side to a pizza on 2 days, but on the 3rd day

they griped at us a bit.

All in all - we got GREAT value for our vouchers and ate like KINGS!
