Not sure about others, but if I see a day I want I book it immediately. To modify you have to get out of that search screen, open your dashboard, wait for it to load, find your reservation, click to modify, wait for it to load. Click the next screen, modify your date, click to check availability, click to get to the points screen, click to get to the guest screen, then click to get to the acceptance screen. Check box and submit, start praying as the blue circle of death spins and hope the dwarfs don’t pop up. After all this, I click to dashboard and hope it’s there. I’ve lost too many hard to get extra days trying to modify…. Thats my reason…
