A whole variety of things could go wrong with your package:
• Delays at the departure airport
• Change of resort
• Change of hotel
• No balcony
• No sea view
• Filthy dirty rooms
• Change of meal plan from waiter service to buffet
• Children’s pool closed etc etc
In these circumstances your travel company cannot blame the airline or the hotel, the fault is their responsibility however the onus is on you to inform your travel company as soon as possible.
It is then the responsibility of your travel company to put things right unless
• It is impossible, or
• It is disproportionately costly
Even so you will be entitled to compensation unless it was for reasons beyond the control of your travel company, or it was your fault.
Even if your travel company does put things right you be entitled to compensation for any period during which there was a problem e.g. if you were promised a room with a balcony and it took two days for this to be sorted out you would get compensation.
If your travel company does not put things right or an immediate remedy is required you are entitled to take things into your own hands and sort it out yourself – and be able to claim compensation for any expenses you incurred.
If there is a significant problem with your package your travel company must make suitable alternative arrangements e.g. by moving you to another hotel. The alternative arrangements must be of an equivalent or higher quality. If necessary your travel company must take you home again if this is agreed.
If the alternative arrangements are inferior you are entitled to a price reduction
