Hi Craig
Welcome to the Forum and all the info you require to make your holiday a good one.
Disputes with the owners happens very occasionaly, but usually get sorted before holidays, I can't comment on Gallini as we have never stayed there, we usually book through Olympic or Libra as we like to be nearer to the sea and never had a problem(touch wood ).
Likewise yourselves with Manos ,your'll have to wait until your out there to ask.
