Please stop reading if not interested in first world problem. We booked 1 week activity holiday for family of 4 on Costa Brava including use of 3 bedroom house with plunge pool, patio, additional outdoors kitchen and a herb garden, and aircon throughout house. Arrived to find 4 bedroom house with only 1 lonely aircon in central living area, no pool, no patio, no herb garden no outdoors kitchen. When challenged the organiser said the house represented an upgrade as "much nicer than the original one". We were all looking forward to pool in particular. I know I am not unreasonable to ask for partial refund - but how much is reasonable? How much in proportion of total holiday price excluding flights is a pool and outdoors living area worth during 1 week holiday?
