Hi everyone!We are trying to book a hotel room block for our wedding. The hotel we really want to use will only let you block a set of 25 rooms without being charged. So, if I want to block 50 rooms and only 30 end up being booked, then I'll be responsible for paying for the 20 unused rooms. Is this typical hotel practice? I have no idea how many rooms to block now, especially since I don't know how many people are coming to the wedding yet!We are inviting around 300 people. How many hotel rooms would you block (about 70% will be from out of town)?
