The Hostaway software allows you to update the minimum stay by the dashboard on most channels. Expedia can receive these minimum stay updates based on the limitations set within your Expedia account.
Ask your Expedia account manager what your minimum LOS and maximum LOS settings are in your account. These are usually set between 0 and 26 days min/max. This means that in the Hostaway software, you can use per day a value between 0 and 26 days.
When the minimum is set by Expedia to 16 and you try to update 13 days, it will not process and your connection might be corrupted. Always test your minimum and maximum stay after you've established a new Expedia connection.
