Bare boating in the Ionian

Got a message from brother in law in Macau, how do you fancy chartering in the Ionian this summer, didnt need to ask twice, got on to Sailing Holidays, managed to get a 46 ft Bav for the 2 weeks, 4 of us and 4 of them plus the old trout, (mother in law!!)4 cabins etc, cant wait!! Done 3 flots before so know prety well where to go but am wondering what it will be like without a crew reserving spaces for us!
