If I use 2 adult lunch vouchers at Rainforest Cafe, can I pay for kids w/gc??

[disney4us2002]

I earned giftcertificates and have $50 for Rainforest Cafe, but oh my gosh, looking at the menu I can see that $50 is nowhere near enough. So if I buy 2 adult $29.50 lunch vouchers thru connections, can I pay for the kids meals (actually I have 3 kids and one is 13) using the gift certificates? Is one or the other considered a 'coupon' and therefore cannot be used together?

I'm sorry about a new thread for this but I reviewed the previous posts about RFC and connections and never got the info I needed.

Any info is great! Carla
