I've assembled the hardware I want to use for my travel hotel room hotspot project. The first pic shows the 3800mAh Raspberry Pi Club UPS battery installed under the LCD case https://www.amazon.com/gp/product/B01JLEO9UC/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1. I'm not sure how useful it would be with a power outage that takes down the hotel WiFi, but it's also not terribly expensive. The second photo is of The 3.5" LCD screen/case/RPi 3/Cana Kit Power supply kit assembled with 3 WiFi antennas. https://www.amazon.com/gp/product/B01LX526QA/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 Who ever packaged the kit was careless, because even though the 3.5" screen comes with it's own case, there is a second, non-LCD compatible RPi 1 B+/RPi2/Rpi3 case in the kit. I plan to use it to finally put my RPi 1 B+ server in a case (also with a UPS, even though w/o a UPS for the attached external storage and another for the network, there might not be much point (the battery does have a second, power only, full sized USB). Not to digress, this week a friend showed me an external, WD, USB powered 2Tb hard drive he bought, probably a product of WDs Pi specific external hard drives.

The 3 WiFi antennas are intended for 1) Incoming connection from the hotel/convention center/etc 2) Outgoing link that goes through my home VPN 3) Guest connection for any one else sharing the room that does not go through my VPN. I want the wired Ethernet to be configurable as either WAN or LAN.

The battery pack is meant to bolt underneath a Pi using the regular mounting holes via standoffs. Use the longer, smaller diameter screws from the case kit to screw into the standoffs from the battery kit as the screws from the battery kit are too short to go through the bottom of the case. There are four clear plastic spacers the need to go between the RPi board and the bottom plate of the case.

I intend to rely heavily on the work of +Daniel Frey on his own travel hotspot project, https://github.com/dmfrey/pifi, based on Raspbian. Rather than release a distro, you can see Dan's Github is more a set of instructions, i.e., start with Raspian, the install this package and configure it thus. Any additions I make, i.e., VPN support, I intend to contribute back. To use the LCD, you need to download a modified Raspian from the manufacturer with the drivers already built in. The genesis of this project was a hotel I and some friends stayed in a few years back. The room included "free WiFi", but included a web based login that would only work for one device and we each came with at least a phone and a laptop (so none of us used the WiFi, we spent little time in the room except to sleep that trip, so it was not missed). The built in LCD would allow you to navigate past a login screen w/o needing to connect the room's TV as a monitor (though I'm pretty sure it's not a touchscreen, so you still need a compact keyboard/mouse), certainly the LCD and the battery could be eliminated to reduce costs. Using a VPN into my home network, I would be using my home network's router for security, but I will experiment with iptables locally.

This is essentially a 4G hotspot for people who don't use much data (you start to pay each month if you go over). I'm thinking it might be worth the one time $20-$60 one time equipment fee (depending on where you live and how much they can upsell you) to carry around a hotspot to the occasion hotel or convention floor. Has anyone had experience with FreedomPop?
