I like how easy it was to use with our staff, but also really enjoyed being able to check in customers by hand as well! It just made life easier when we had lots of people coming through at once or needing multiple tours booked within one day because they were all running late!! Sometimes you can't do everything manually though so this could be an issue if your having issues getting things done fast enough from MARS. If anyone reading has never used mars before then try out their demo first…
