Hotel's Wifi Login-Confirmation Page Times-Out

I'm staying in a hotel in a foreign country for a few months. The hotel's wifi, once connected to, pops-up a login page. Once logged in, it presents the "login confirmation" page, which mentions it should not be closed or else the session will be disconnected. Problem: It will constanly re-prompt me to login on my iPad or iPhone.

I believe it is because the wifi system detects that the login-confirmation page is "not active" or closed and thus times-out. I don't believe this is a problem with the iPad/iPhone itself, but rather the way they do their login-confirmation page. But dealing with the hotel staff on this is not easy (language barrier), and they don't seem very knowledgeable about their wifi anyway. Was hoping someone might know a "trick" to get around this.

Here's some other things I notice:

1) The problem does not happen at all on my laptop... Perhaps because it senses that the login-confirmation page stays "open"? (I just leave the login page open on a tab within Chrome). Somehow on a laptop it knows the page is open, but on iOS it does not?

2) The problem on iPad/iPhone happens with both Safari and Chrome.

3) On the iPad/iPhone... I do notice if I constantly click on the tab that contains the login-confirmation... About every minute or so... Then it will not re-prompt me to login. Of course I don't want to keep having to do this.

4) I know I can also share my laptop's wifi to my iPad, but I'd prefer not to do this.
