Zero, since I have never had a need to go to that stage.fountainhall wrote: I wonder how many times you have received refunds or additional perks after writing such a review.
The last time a hotel tried to add charges was in Europe & it was resolved in my favour at the front desk.
I see the sequence of events as:
1 Discuss with front desk
2 Discuss with the management, politely, then assertively. Threaten to write reviews if necessary.
3 Discuss with the booking site
4 Write reviews. This is more done for the good of society than my personal benefit. However hotel bookings ARE affected by review scores & if everyone who is ambushed with extra charges writes a scathing review, customers can see it and hotels will have to stop the scams. It's all about allowing others to make informed choices and pressurizing the hotels to behave. Then what goes round comes round.
Most booking websites have a box for all the key rules & I just expect hotels to declare all material charges in that location.
Saying the room is 2000 baht (for example) & then finding it is nearly 2900 baht when you arrive is just dishonest.
I expect all transactions to be fair to both parties and once it becomes unfair, I challenge them.
