We stayed at Riverside for our honeymoon and had a wonderful time! We requested the mansion section, and had no problem getting it (although you should definitely tell your friends to request it on their ressie and also note that it's their honeymoon). They gave us a waterview (of a fountain) and we paid the extra $ to get a king bed (although I have a feeling they'd have given it to us for free anyway). I think it's a great resort for honeymooners because it has so much to offer. You have (almost) nightly entertainment of Bob Jackson in the lounge, carriage rides through the resort, boat rides to downtown disney and just plain beautiful landscaping!! It was great to walk around (especially at night) and just take it all in. There's also a butterfly garden at one of the mansions (I think Acadian House) that is really beautiful.
