Solo trips are not for everyone -- but they are definitely for me!
I've spent a lot of solo time at DLR -- I really love it. I still prefer riding certain rides with friends, and I usually prefer dining with friends (especially if it's at a table service location), but otherwise... I am fine on my own and have actually grown to favor solo trips in many ways! I take a lot of photos -- meaning I can rack up something like 700+ photos in just one day, or a couple of thousand photos over the course of a few days -- and I would not be able to do that if I had people with me. I need to be by myself to seek out photo opportunities and get in "the zone." I don't want to inconvenience anyone by stopping every few minutes to study an interesting detail and frame it 'just so,' nor do I want to be interrupted and bothered when I am on photo mission.
When I first had several hours of solo time in the parks back in 2008, it felt a bit strange. I just wasn't used to it after decades of visiting Disneyland with friends or family, and I couldn't fully embrace it. The next occasion for me to have solo time was in 2010, and that's when it started to click! I had something like 2-1/2 days to myself to wander around and do what I wanted, at my own pace. It was glorious. I was with friends at the beginning and end of the trip, but those middle days were all mine!
Ever since then I have either done completely solo trips -- not even meeting up with friends for a meal -- or 90% solo trips, in which friends are with me at the start and then I have several days to myself to explore. I do end up chatting with other people in line, or at the Disney hotels, or wherever. It's not that I wander around with a scowl on my face and a "STAY AWAY" sign!
But I love my solo trips so much, whether they are just day trips or multi-day trips.
I think I trained myself to adapt to solo trips in my younger years, during visits to other places, so it was just a natural progression for me to fly solo at DLR. Now that I have gotten so used to solo time, I have to actually get into a different mindset to do a "friend trip." Friend trips are great and I have had many wonderful outings in the parks with friends, but it does require shifting my mood, expectations, plans, etc., a bit. Whereas I can be silent and not talk to someone (if I don't feel like talking) during a solo trip, I have to actually interact and have conversations when I am with friends!
