One of the bulkier items to pack is a hair dryer. It takes up a lot of room, is hard to squeeze in a carry-on bag, and can be unnecessary.
Why? Most hotels have them. So do most VRBO rentals. If you really don't know, check the website or call the place where you're staying. Maybe it isn't exactly like the one you use in your own home, but chances are it will work fine.
Save the room in your bag for something else...like shoes!
