IHG hotels open reservations a bit less than a year in advance. If you're trying to reserve a hotel room during a big event, you know how important it can be to book right when availability comes online.
Here's a quick trick to book a day ahead of everyone else.
First, let's say you want to book March 3-4, but March 4 isn't open yet. When you select March 3 as your start date, you hit a dead end and get an error when you try to submit the form.
The trick is to select another date; for example, March 2.
Now, when you hit the results screen, click on "Change Search".
Then you can select "March 3" as your check-in date and your check out date will be set to March 4.
