I'd get MUCH faster than that simply by tethering my laptop to my iPhone and using the 3G.
I just ran Speed Test and my 3G connection returns 20.19Mbps down and 13.85Mbps up.
I almost never use hotel wi fi unless it is free or very cheap. However uploading the amount of data you are talking about would be expensive - my mobile plan (like most NZ plans) is data capped. My included limit is 2.5Gb/month. Over that and you're paying 20cents a Mb.
