Whatever status you have with IHG, if you might stay at an IHG property over the next 90 days from when you sign up with this link, you can attin Spire Elite, their top tier status. This allows you to have free upgrades at their properties, including Holiday Inn, Crowne Plaza, Intercontinental, Indigo and many others. To keep the status, instead of having to stay until the end of January for a total of 75 nights, you will only have to stay 10 to keep the status in 2019! If you only spend 5 nights (instead of 40), you keep platinum elite (which also makes you eligible for free upgrades) for 2019.
For every stay, you'll get 100% more IHG points if you use cash to stay. Also, you get early check in (10am) and late check out (2pm).
You have nothing to lose, so go for it!
