My experiences taught me that this type of activity is very essential to validate how I felt at my next home town. Absolutely a great service for those who like to become familiar with the quality of life that they will have in the future.
Your employer will pay for this service especially when they like you to become successful at your new home assignment. There is nothing more important to high performing employer than your success in job responsibilities, cultural adjustment and ROI of their investment to your expatriate status.
Pre-decision tour and community immersion works well when you are one of those successful expats or families that will enjoy the experience and amenities of the new home environment.
