Welcome and Congratulations on planning your wedding!!
Well, DH and I chose the Intimate Wedding because I wanted a Disney wedding and we both wanted a small wedding. The Intimate limit has increased I believe to 18 guests, when we did it, it was 8 guests and so that's what we had. It was great because if a family member who we didn't particularly want there in the first place complained we could just blame Disney and say it was limited to 8 guests

We couldn't narrow down our friends so we let Disney do it for us
Then, my mom passed unexpectedly 4 months before the wedding. I was honestly relieved that we had planned a small wedding, I couldn't have gotten through a big wedding without her and we canceled our at-home reception as well. That had a guest list of 132 and growing before we canceled.
So, I have to tell you the Intimate was PERFECT! It was just our immediate families and my best friend (who introduced DH and me and is like a sister to me). It was personal, elegant, I didn't have to entertain anyone, I could just enjoy the time with my new hubby. I know lots of people prefer to have many friends and family members all around on their wedding day, but for us, having it be so small was exactly what we wanted.
We had a rehearsal dinner with just us, DH's parents, my father, and my niece (my MOH). We didn't do a dinner or a dessert party after the wedding, but we hosted brunch the day after and everyone loved that! We also went to MK with whichever guests wanted to tag along and then to PI with friends the night after the wedding.
One of the best parts of the event for me was after the ceremony, cake, and all of the pictures, we said good-bye to everyone and headed up to our room. We had a private dinner in our room and it was completely romantic
Best Wishes and I know you will get a lot of great advice on these boards!!
