I have a two-fold issue here; my wife and son are eager to go on our first ever cruise but I am afraid of my motion sickness....

Although my DR told me I should be ok but I may want to stick to a short cruise first. I am looking for a cruise besides Disney for our first time. We're waiting for my son to graduate high school for that.
My question is, whom should I use to help us with the planning etc? I have planned all of our trips to WDW and used
AAA several times but other than that, I've done them myself. Cruises though....never been on one and surely never planned one.
My goal is to leave out of Port Canaveral [so I can justify sneaking a few days at WDW].

I just don't know which cruise line to choose or which ones are family friendly etc.
Any help would be welcomed with open arms...
Thanks.
