it all depends on the AI resort. They all vary in what is included and what is not included in their packages. Take Dreams for instance. they charge you a ceremony and reception set up fee of $28 each, total $56 per guest only staying at the resort. But, for outside guest not staying at the resort, they or you would have to purchase a Day Pass for them, which is $89. Depending on which package you choose, you can have a 3-5 course meal, or buffet, which is an additional cost per person over 20 guest! Again, depending on what package you choose. I estimate approx. 80-100 guest. Which for our budget, is way too much.. BUT, this is still cheaper, if we didn't have it at an AI resort.
