I contacted the 2 decent hotels near my venue for a block of 30 rooms. One came back saying they only had 15 due to another event that weekend and the other said they require a $1500 deposit due one month after blocking and would refund it if 75% were booked by 1 month prior to the wedding. Is this normal? I don't think we'll have a problem getting (at least) 30 booked but I'm not sure I want to put that much down as a deposit when there are so many other vendors to book and pay in the next year. Thoughts?
