Hi Marks,
We go self catering now and love it. Some things that I have found useful to bring out with you are tea towels as they are not always supplied,scourer, sponge kitchen wipes & cling film, (I always overwrap suntan lotions,shampoo etc in this), pegs, I think that is about it

All other things can be bought from Tansas. One other thing if you want fruit squash bring it with you as you cannot buy it in the supermarket.
We love going out to eat so many great places to choose from. I have spoken to quite a lot of people who have gone all inclusive and I have not had glowing reports from them.
Jean
