I know the problem, and my advice? Don't let other (or the lack of others wanting to go with you) stand in the way of your own plans and wishes! I mean, if you don't go, you'll miss out on the thing you'ld love to do
because of other people.
Allthough going with others definately has it's benefits, going solo also has it's pro's. You can do whatever you like, don't have to think about any other person and what they might want or dislike. Being solo does make it easier to get in contact with others, which can be a real bonus.
Somehow I always ended up with this problem. First with me only being able to get off from work at the moment my friends couldn't get out of there study. So I went to Greece on my own. Had a blast and because of going solo I ended up at a greek families home having diner.
In 2005 I was desperately wanting to go to Australia, but again; no one wanted to go or could/wanted to afford the trip. I went solo again, and am
so in love with the place. I would have missed out on so much if I hadn't gone.
And now? I want to go to DWD, and most people think I'm ready to go into a mental ward. First of all, why go to DWD if you've got
Disneyland Paris "around the corner" (well, 2 countries away), and second of all; why go to any Disney-thing for longer than 2 days anyway? So I ended up booking a solo trip. 8 Days of fun in September.

On one part I'm a bit nervous, most of all because of it being my first trip with a new wheelchair. But my curiousity definately wins! I can't stop myself from drowning online in all kinds of topics to get into the athmosphere.
If there is one lesson I've learned; "it can all be over by tomorrow, so you'ld better start living your dreams today. " And let's be honest; isn't it better to have some doubt and/or fear and overcome that, than not going and having to wander what could have been? What's the worst thing that can happen if you go alone? You won't like it? Doubt it! You might find you're not a person for solo trips, well OK than you'll know for sure but still had the disney-time.
I'm being a bit of a copycat, but I would have to join the others and say; go!
