What are my options:
1.Install the esim and take out the sim card. Easy, safe, but I might lose or damage my sim card.
2. Install the esim and disable the sim card. How do I disable the sim so it would not connect to the internet or receive sms?

Thanks
Sims/esims data can be disabled in the settings to prevent roaming data charges. You could retrieve the messages by connecting to the hotel WiFi.

iPhones can be configured to use IMS over WiFI with the Telekom sim data disabled. Wifi is turned on, the data of the local esim is used to retrieve the messages for the number associated with the Telekom sim.
