I'm just wondering what's your experience to book a hotel.
Most of the time I'll book my flights tickets when there are special prices.
One year or two before I'll check on a regular base what these prices are.
Of course they can go up and down but most off the time you see a returning special price.

Only with booking a Hotel it seems to be impossible when it's the right time to book.
Of course not in a holiday season but there are a lot of discounts ,codes which suddenly appeared.

For instance do you make a booking 1 year before or a couple of months or even a very last minute.
I'll know it also depends how many free rooms the hotel have and many othe parameters.
Still I'm looking forward to your strategy.
