Why not take less with you and make the most of the extra allowance to go shopping. Summer clothes are light, you can wear the jumper/fleece you may need for the evenings. If you are staying in a villa, it is no hassle to put one wash on mid stay if needed, but even without, I think most people bring home unused clothes from holiday [msneek]
I often use a porter at Orlando from the car park to check in... worth every penny!
