Have you seen the resort yet? If by the "garden" you mean the grass area between the preferred side rooms and the restaurants, then my only concern for you is the mosquito's! They are bad in the grass- or at least at night and in November. We took just a few pictures there as the sun was going down and I got eaten alive. So that may be a concern for you but you can always have them spray. Also ask them about the dance floor and I'm not sure you can have music late at night there? I'm not sure if you've seen the "orange lounge area", but it's not very private as it's right in front of the restaurants- but probably not a problem for a cocktail hour. Sorry, hope this helps- it was only my experience. I had my reception at Las Olas/ Castaways. It's open on all sides but has a tall roof and lattice over the terraces- wind was not a problem but the breeze a was nice relief from all the dancing! So it was half indoors and half outdoors- perfect for us. The only problem with having it here was that they the reception can not start any sooner than 8pm. (they close the restaurant at 6 and then only have 2 hours for set-up) If you have your heart set on an outdoor reception, you can always have it on the Carnival Terrace outside the buffet or the pool deck if you don't have too many guests.
