Is the "double bed" too small for two adults? Some hotels said 'double', but I found them almost like 'queen'.
The junior suites at Hyatt Place Colorado Springs have either one king bed or two double beds. Many of our guests do sleep two adults in a double without complaint, but it's ultimately a matter of individual preference. Always feel free to request a king, even when they are not available, as we often have last-minute cancellations.
It's definitely double size. If you're average size adults, you'll fit fine.
