I know there have been threads about this but thought it would be easier to start a new one. Anyway, I'm heading to the Don Pablo next month so I emailed the hotel to ask whether there is free transport available. Apparently this is available if you have booked through the Melia Hotels website and should be booked online. I haven't tried this yet, I actually booked over the phone as I had loyalty vouchers to redeem but hopefully this still applies to me. I'll let you all know how I get on.
