Congrats on your upcoming wedding/honeymoon
We used the Silver package on our honeymoon in Feb. 2003, and the Gold package this past Jan. It was just the 2 of us. We enjoyed both packages, but preferred the Gold. I priced everything out this last trip because I was concerned about wasting $ by using the Gold. We managed to save slightly more than $1000 by using the plan versus paying for everything separately. I also took into account the $ we would have saved by going on the Silver plan which had a discount at that time, and we still came out ahead with the Gold.
Of course, you can certainly save $ with an AP and the discounts there... However, we go only once a year and rarely go out - saving for Disney of course

I am a coupon-clipping, $-saving fiend (except where Disney is concerned)! We also go in value season, so we don't have long waits in the parks, plus the parks close early leaving plenty of time for dinner, Cirque, etc. We did a lot this last trip - we did eat 3 meals a day - lots of character bfasts, nice lunches, and all of the 2 wish places for dinner. We were getting sick of it by the last day (our 8th). We like to eat, but neither of us is overweight, we both work out a lot and eat healthy normally. This was our super splurge.
We used the recreation too - we took out the water mice once, went parasailing, did Keys to the Kingdom, Backstage Safari, and Cirque. However we were on the go constantly. For us it worked, although probably not for everyone.
We're hoping to go back this Jan. on the Gold again. We loved the plan - otherwise we'd never eat at those places, or try the tours and other activities. I planned extensively before this last trip (how to get where and when and how much time each thing would take), and will plan again - but I like to plan
So bottom line is that you can definitely get your $'s worth on the plan, but it does take a lot of planning and really deciding what suits your own needs best. HTH!
