Of course you can bring two. Though the 2nd unit I describe is probably half the weight and size of a typical laptop, if not less. Hell, there are fullblown thin laptops that are close to half the weight and size of ordinary laptops, they just don't have CDs or floppies or much battery.

I'm talking about removing the motherboard, drives, memory, battery and possibly power supply from the package. It's a lot of the weight.

As for a small router, you can do that, but that's another box (and wall wart) to bring, and cables to bring, and it may not be so easy to set up depending on the login system. Connection sharing and a single cable (or no cable at all) makes more sense.

In hotels with wireless that charge for access, you only get one computer MAC per charge. Hotels that give it free are not a problem. Of course I prefer that -- it seems the fancier the hotel the more likely they are to charge you for internet -- but you don't always get it. I've been in some hotels that give you access based on room number. I have not tried these to see if they will let two computers on in the same room.

As noted, a longer term vision is that hotel rooms start to become equipped with computer displays. Probably the HDTV they'll all soon have as those drop in price, but even a cheap $200 flat panel would be handy to have in hotels. Both for couples as I describe, and even for those who want to have two screens, as modern laptops will mostly do.

They could also have a simple web surfing appliance, with real screen and keyboard. Many hotel rooms offer web surfing on the TV, at a ridiculously low resolution and often for a ridiculously high price. It may be that the hotel HDTVs all have a web-surf appliance mode in them, since that's cheap to do. Sadly it will probably be high priced.
