For a single hotel room with just 4-6 devices, yeah, even RB951-2n is sufficient.
If you wanted to manage an entire floor though with a single router, it wouldn't be - You'd need at least RB951Ui-2HnD.
As for mAP or cAP... They could work without switches, if the different client devices have a WiFi bridge attached. If you get a small enough bridge for each device (the size of mAP or worst - slightly larger), the whole thing will look even more prestige than RB951-2n with cables running around. You could
get another mAP for each device, or perhaps use something like this
if you want the bridges to be a little cheaper.
