First time family visit in August - me and my son (12), my sister and her son (14) and our parents (60s). We're staying on International Drive and will not be driving. I know it will be HOT and have read tips that say get to the parks early, go back to hotel during hottest part of day and head out again in the evening. Is this practical using shuttle buses - or local transport - from IDrive? I'd be very grateful for advice.
