Past this:

• Use captive Wi-Fi networks on your iPhone or iPad - Apple Support

…The hotel network or the portal is probably malfunctioning, or it needs an update.

Since this is macOS, you can try to force the portal to appear by using the following Terminal command to launch the captive portal mini-browser (CNA):

sudo /System/Library/CoreServices/Captive\ Network\ Assistant.app/Contents/MacOS/Captive\ Network\ Assistant

…the sudo command requires an admin password, and syntax including spaces and slashes matter.

Failing that CNA attempt, try connecting to the captive portal while the Mac is booted in Safe Mode, as his shuts down most add-ons including add-on security apps, add-on firewall apps, add-on VPN apps, and flushes the caches.

Then… Ask the front desk.

For the Wi-Fi network administrators still reading along here, check for updates to your captive portal gear, a d review the following:

• https://captivebehavior.wballiance.com/
• How to modernize your captive network - Discover - Apple Developer

point your browser at either

captive.apple.com

Or

NeverSSL.com

This will wake up the hotel’s captive portal.

Open your browser and navigate to 1.1.1.1

This should force open the wifi login screen.

Same here. I've always been able to sort it with some combination of quitting/restarting the browser, forgetting and reconnecting to the Wi-Fi network, or rebooting the Mac.

Largely because the whole captive portal scheme is being very shady and intentionally intercepting and replacing network traffic that isn’t meant to be intercepted and replaced.

Getting this interception and substitution working across myriad permutations of browsers and clients, too.

Too often compounded by the portal implementors just winging it on a too-small budget, as well.

And all while vendors are trying to avoid these captive portals becoming the basis for exploits.

Or the particular networks or captive portals being old or buggy or malfunctioning, or using older and deprecated schemes.

Unlikely in my experience. I've had trouble with captive WiFi for at least 13 years on Macs, iPhones and iPads. I've lost count of the times I've been unable to connect in hotels, airports, cafes and client sites while friends and colleagues on non-Apple kit had no trouble at all. I had to buy a PC for one contract because I needed internet in the evenings and neither my Mac or phone would connect to the hotel hotspot. Needless to say Windows just got on with it.

This comes up and then it stays empty.
