My first time to Europe I also went alone and LOVED it!!! I made friends when i wanted to be around other people and when i got tired of them i went my own way!! You can do what you want when you want!!
People think O-man your going alone are you crazy, but it really is not that hard or scary just keep your eyes open and you will be fine!
On a side note I should be in Ireland in Killarney In June and I hope through Oct. If you want to get together?
also with TP behind you, you are never alone there is always a TP member close by!! I would have been a little more scared if I did not have my secound family here!!
