Try the Couch 2 5K program, or Run Disney's Jeff Galloway 5K training program. Both are easy no-pressure ways to transition into running without risk of injury. My husband and I are new runners and will be doing the CC5K. I did it last August by myself as well. Would be happy to answer any questions you have. Some of the things that might be obvious - it is HOT and HUMID, so if you're not used to that be kind to yourself. It's a neat experience, but it's not scenic - I first imagined running along a beautiful beach path or nestled among palm trees, nope! The course is from the bike rental place towards Serenity Bay, around the bike path loop, and up/back the runway. Neat to see but definitely not 'scenic', and no breeze. There is water in one place along the way (although you pass that point 2 or 3 times, so you can drink more frequently), but if you tend to drink a lot running I'd bring some with you. The timing seems to vary by cruise, but I had time to run it (really slowly!), shower, change, and have an entire day at the beach. My family waited for me between the bathrooms and the bike rental place to take pictures of my finish and cheer me on. Only souveniers of the run available are plain cotton t-shirts with the "CC5k" logo on them - I wish there were a fitted or technical shirt, even if you had to pay a premium.
Most important CC5K tip - in my book, you get an extra guilt-free Konk Kooler afterwards
ETA: I'm more of a solo runner (will probably even ditch the husband!), but would love company at the meeting point beforehand, on the walk to the starting point, and would be more than happy to cheer you on at the end!
