Well, it wasn't that hard for me, but I don't have any problem doing things by myself. I decided that I wanted to go back, had gone once before with mother and sister, didn't know anyone else that wanted to go, so I just booked the trip for myself. Though the real reason that it crossed my mind in the first place was because of this board. That trip ended up being semi-solo, my stepmother joined me halfway through. But I have been back once since, and am going again really soon.
Some people have a hard time doing things themselves, but if you don't then you should be fine. Don't worry about what anyone else says, I got a few comments the first time I went by myself, but by now, everyone knows that I have no problem with it and they don't say anything, my friends at least.
