[ale] Raspberry pi standalone hotspot/apache server - how insane?

[neal at mnopltd.com (neal at mnopltd.com)]

So, if one was headed out on an extended cruise, and one wanted to do a 
couple of things:

1) have a standalone hotspot to allow an android phone and a Roku stick 
to communicate so the phone could cast some learning videos to the TV.  
(tai-chi/qigong - long cruise)

2) have a that hotspot also provide a rudimentary webserver, so that 
static html pages could be served up to some number of people, 
completely independent of the ship's Wifi.

It looks like a raspberry pi 3 could readily do that.

How much work to set that up?  Where might one find the best deal in 
town on one?

Having never worked with one,  I'm guessing that one can find a base 
linux, and the hdmi port will drive a display, and one can stick a USB 
keyboard and mouse on it, and then it's pretty much a small linux box?
