Earlier this year we had an apartment booked through Icmeler Online and when our daughter wanted to join us for a week, I.O said no problem, the price is for the apartment, and we had a great week with her. She's booked herself another fortnight, in October, through Thompsons, and presumed we could do the same, joining HER for a week. We can get flights, and we'd love to do it, but does the fact that she's paid underoccupancy supplement mean this would be ok? Or would Thompsons charge us more again than she's already paid.?
