I've been using Touringplans since they first built their website!
Did you buy a 1 year subscription? If so, here's how to make your own itinerary:
First, print or at least have open their plan. This is teh BEST plan of attack and should be your basis.
Next, go to Personalized Touring Plans and Create A New Plan. Complete this plan using the original as your base and simply not including the rides you don't want. I don't recommend swapping them for somehting else; better to follow their Plan minus the rides you don't want,
then start adding rides you want but UG didn't include.
Sure can! I currently have 8-10 of my very own, personalize dplans through them! See above...
