Nice read, Mary!
I liked the chuckle at the end, lol. It sounded clear and conversational, but I felt like there should be a little more energy to the read.
A suggestion is to vary your pitch in your list (especially You’ll have over 700 airlines, over 45,000 hotels, and over 50 rental car companies all at your fingertips.), but don’t pause after each comma — by varying your pitch, you can make the read flow better without having to micro-pause. Make sense?
I hope this helps!
