How did you come up with the landing page's headline? TBH, I don't feel the desire to sign up, you want to work on your headline a bit, have you tested other variations?
Try to build desire on your LP. Put yourself into those visitors' shoes, just imagine the struggle that they work 40+ hrs/week and still can't afford a great vacation... What would you want to hear as a solution?
Regarding your ads... Maybe start split testing just the ad copy first. Or Start split testing the layout, just one component at a time, otherwise you'll be wondering why a certain version did better than the rest...
It seems you're doing pretty great as being your first campaign.
Gather more data tomorrow - if you see the same placements/carrier (has you said) giving best results - segment them right away.
as fbqueen pointed out, that headline is blunt - try appealing to your target's pain points. that's a feature - not a benefit.
