Hi and welcome to the forum!
After becoming engaged, the first thing that I did was decide on a location and accommodations. Once that part is done, the rest will seem easy! That being said, I think that the size of the resort is up to your own personal preference. It was very important to us to have a private, intimate wedding, so, we ended up renting out a smaller place that could accommodate all of our guests.
Let us know what we can do to help you in the planning process!
