i know others have had a suite wedding/talked about this to save money but one thing you need to be aware of is if youre caught you can be thrown out of your hotel & disney. that would be so embarrasing. per disney policy all wedding ceremonies there have to go through dftw. ntm some vendors like officiants & photographers disney brides regularly use wont want to risk their reputation with disney.
you might want to consider an intimate dftw or a wedding off site ie leu gardens in orlando.
as for the suites there are some good pictures of them at suite disney .com
most of the deluxe hotels (with these suites) offer in room dining or private dining with meals &/or hospitality trays.
