Sounds like you need to get a few more miles in your legs before trying it for real.
The only real issue with camping for me is I like having the tent setup while it's still light out whereas you can rock up to a youth hostel/hotel at any time and just flop down. Oh and you have to carry another couple of kilos of kit. If you're fit enough, geared appropriately then you should be ok.
