I have used and continue to use booking.com a lot but my confidence has been a bit shaken by:1) Getting messages supposedly from the hotel saying I need to pay them directly or they would cancel the booking. These were scams from someone intercepting the hotels account. I feel booking.com should do more to strengthen the hotel's cyber security if they continue to use them.2) I have been to two highly rated hotels recently and been very disappointed. Either the reviews were hype from the hotel or the people giving them have very low expectations.
