Do not get stuck on promo price: limit to quota
The price of promo helps fill the first room, but indefinitely can withstand overnight income.
The price of promos at the beginning of sales is often used to fish for reservations. The thing is, if the demand comes in heavy, all the rooms could run out of promos and average prices that night fall.
# # Use quota
Set the number of rooms that can be sold at promo prices, for example a fraction of the total room. Once the quota runs out, the next room is automatically sold for normal prices.
# # Separate promos per date
A promo for quiet weekdays doesn't need to apply on weekends or holidays.
# # Evaluate results
Compare the overnight income to promos and no promos. A good promotion adds room to sale without lowering total income.
Promo is a tool for starting sales, not your new price of property.
