EA and coupons from different sources

[yoopermom]

The Disney "coupon" (which is actually a contract #) states, "may not be combined with any other discounts or promotions". Does this mean that I can't use an entertainment coupon, also? It allows me to input both numbers, and comes up with discounts showing for both, but I don't want to have trouble once we're there. We're going 12/26-1/4 and with both discounts would be looking at $188 total. Thanks!

The Entertainment Coupon states it must be used with the EB code. National's reservation system is allowing the "illegal coupons" and so far they are honoring the rates. Make sure you bring a printout of your reservation.
