Most of you seasoned travelers may know this already, but I just learned a cool trick!!
I had booked two hotel rooms for 3 adults by mistake (fully refundable rate, thank goodness!!) I got distracted during the payment method entry and booked twice.
Turns out one set of kids can go with us to Bermuda. I went in to change one room to 2 adults and 2 kids, and discovered the price had dropped. I was able to modify both room reservations. Due to price drop and 2 adults rather than 3, one room dropped $40. Our room with 3 adults dropped $15. That will almost pay for our ride from airport to hotel!! I'm going to check on our Feb reservations as well.
