Anyone else received an invite to this hotel as part of its rebranding to a DoubleTree?

Had an email through today inviting me to attend...Not sure if it went out to everyone or just because I have an upcoming stay this month or if it is a simple marketing mailing to all and sundry.

Apparently some prizes and offers during the event. Anyone else going?

I'll update here if I do go and find out anything of relevance.
