Last year we did a 3 week road trip from LA, to San Francisco, to Las Vegas, to San Diego and had an amazing time. This year, we were thinking about doing a road trip in Florida (Orlando -> Daytona -> down the coast -> Miami -> Keys -> up the West Coast -> finish trip in Orlando again). Originally we had considered August, although September is working out a lot less expensive!
Dates from around 13th - 29th September would work well (2 weeks more or less) - although I was wondering, will the weather still be good at this time of year?? (From last year's September trip, we were surprised that it wasn't as warm as we thought it was going to be - so really looking for a bit more heat this year!)
Also - any suggestions on must see / must do attractions/activities/landmarks would be great. Not sure how long to spend in each location, so just wanted to have an idea before we start planning properly!
