Natively out of the box no it is not possible to do that; however if you are willing to use a windows based computer not a tablet you can cheat somewhat. This is very advanced if your not tech savvy getting it to work maybe very difficult.   There is a website called teamviewer. They will be able to let you set up a remote session on the computer you leave on in the hotel room.  That part is easy enough that their website will tell you all you need.   Now this IP camera will have to be powered. You can use a regular power supply of POE switch. The switch will set you back more than a power supply but if you need to connect more devices a POE switch is a better way to go.   Assuming you have a switch connect camera to switch then Ethernet cord from switch to computer. Connect computer wireless to hotel network. Use the command prompt IPCONFIG to find what the network looks like.  Hopefully it looks like 10.1.10.1. If it does you just need to setup the adhoc network. If it looks like 192.168.1.1  (look at gateway ip)  Then we have to change somethings.

To create the adhoc go into network settings then wired network adapter.  go into properties then advanced tab. Statically assign your pc an ip address.  If network is handing out 192.168.1.1 range disconnect from wifi first. If it is handing out something different than 192.168.1.2 is fine. Set your gateway to 192.168.1.1.  Connect an Ethernet cable to camera from Ethernet port on computer. Power either poe switch of 12vdc.  Now access the camera with IE If the wifi network is in the range of 192.168.1.1 you will need to change ip of camera to 192.168.2.108 Gateway set to 192.168.2.1 and save. Now go back and change ethernet adapter to range  fo IP camera PC IP address is 192.168.2.2 gateway is 192.168.2.1. Now you connect to wifi. Then connect to camera. At this point you should only need to establish the remote session. 

Go to teamviewer.com and setup a remote session on pc. When you leave make sure pc is still on and does not go to sleep. Screen saver is fine. Then on another computer set up the teamviewer and remote back into pc at hotel. You can now login to camera and see it remotely. That is if everything is setup properly.      If my explanation of setup on the adhoc network is not good for you just search the internet for walk though on adhoc setup per OS of a windows based computer. Things look a little different between XP, vista, 7, and 8.

Basically the teamviewer elevates the need to port forward as you are remote into the PC not the camera.
