To check the balance of an Omni Select Guest account, members typically need to log in to their accounts on the Omni Hotels and Resorts website. Once logged in, they should navigate to their profile or account details, where information regarding points or rewards earned is usually displayed. This section will provide insights into the total points accumulated, any recent activity, and potential rewards available for redemption. Additionally, it may also offer information about upcoming stays and special promotions. If additional support or information is needed, it is advisable to explore the Omni Hotels website for any updates regarding account management or rewards tracking.
