The "Franken-Stack" is what happens when an operator tries to solve a relationship problem with a dozen different tools. You end up with a PMS that doesn't talk to your CRM, a CRM that doesn't talk to your Mailchimp, and a Zapier account that is held together by digital duct tape.
The hidden cost of this stack isn't just the $3,500 monthly bill—it's the latency of data. By the time you’ve exported your guest list from your PMS to an Excel sheet to upload it to an email tool, the "moment" is gone.
Real scale happens when your guest data is "live." You should be able to see, in real-time, who your top 10% of spenders are and trigger an automated (but personal) "Thank You" note the moment they check out. If your tech stack is too complex to manage, you won't use it. True hospitality technology should simplify the relationship, not add more tabs to your browser.
