Hotel might have fast Internet but if there are 50 clients connected, the speed will not be that good. Maybe PC, pads an telephones. People have lots of wifi devices that they might use.
Depends on the routers too. Some routers can deliver same speed as the slowest connected device that slows down for all others.
I work from home with my connection of 100/10Mb, real measured mostly 95/10. Work fine, I have no need uploading huge files all the time.
I use wireless. 5Ghz band is a must to get that speed, if router or your computer only support 2.4 Ghz, max speed will slow down to around 20 Mb, maybe slower depending on your computer's wifi card.
5Ghz has not that coverage as 2.4Ghz has.
If most of the others are out when you need to work can be a good thing
