How to Contact Diamond Resorts Customer Service

Trying to get in touch with Diamond Resorts can feel like a whole vacation in itself, and not the relaxing kind. Many members run into issues like navigating high-pressure sales tactics or just trying to book the vacation they were promised. Since Hilton Grand Vacations (HGV) acquired them, things have gotten even more confusing for long-time members trying to figure out who to even call. Don't worry, we've sorted through the mess. You can generally reach them by phone, through the online member portal, or via email. For official information, your best bet is to start at the Hilton Grand Vacations official site.

Tips to Reach Support Faster from Diamond Resorts

  • Call Early: Try calling right when the phone lines open in the morning (around 8 AM ET) to avoid the midday rush.
  • Avoid Mondays: Mondays are typically the busiest day for customer service centers. Try calling mid-week if you can.
  • Use the App: For simple tasks like checking your points balance or making a payment, the app is almost always faster than calling.
  • Have Your Info Ready: Don't make them wait while you search for your member number. Have everything ready to go.

Before You Call: What to Have Ready

Seriously, don't waste your own time. Before you even dial the number, make sure you have your member number and the email address associated with your account right in front of you. Trust me, they will ask for it before they even say hello. If you're calling about a specific charge, have your latest maintenance fee bill or statement handy so you can give them dates and amounts.
