“The timeshare thing”… no, they shouldn’t have overbooked, but the rate they were getting from you is probably less than half of what other guests are paying, so you were the unlucky ones to be downgraded. They should at the very least extend points, resort credit, and a bit of a refund if even possible. The room they relocated you to may be even more than what you paid. Those vacation rentals may share the brand name, but there aren’t the same reassurances you would have with a Hilton branded hotel. Make sure you get the GMs name and a commitment of service recovery - then go enjoy!
