Just as mentioned before with the original destinations are supposed to be Iceland, Italy and Croatia, as all have now been cancelled to avoid with the coronavirus, and they will replace with all-American destinations. RS has pointed out that Chattanooga will be one of the US destinations for Clare's season as the cities will now be revised:
Week 4: Chattanooga, Tennessee
Week 5: Key West, Florida
Week 6: New York, New York
Week 7: Billings, Montana
Week 8: Cody, Wyoming (overnight dates; includes a visit at Yellowstone National Park)
Week 9: Maui, Hawaii ("hometowns")
Week 10: Reno, Nevada (Meet the Parents and Last Chance Dates)
As the changes for Clare's season depending on travel with fears of coronavirus, it will have "hometown dates" and "meet the parents" for the final two, just like in Kaitlyn's season, where the final two men will not be eliminated and have still to meet Clare's family in the mainland.
I would think the fake hometown dates would be in Maui, Hawaii and MTPs in Reno, Nevada with the potential FRC will be located around Lake Tahoe.
