Bumping this thread because it has not yet received a response.
edited to add: I see now that member Xerantheum's last post on the site was April 2021. I wonder if anyone else has ideas about which tree this might be so that it can be moved to the correct database entry?
From pics it's hard to tell which of the pink trumpet trees it could be. I did a Google search to see if it was mentioned anywhere in connection with that hotel but didn't find anything.
Name: Suzanne/Sue Sebastopol, CA (Zone 9a) Sunset Zone 15
Without closeups of the leaves and blooms, it's so hard to get a defining ID.
I thought the blooms looked too pale pink to be Handroanthus impetiginosum and felt it matched the lighter pink of the Tabebuia heterophylla Lin linked.
