I am thinking of going on my first solo trip in December of 2014. However, I will be in college, so I won't have much money.
I'd like to keep the cost around 1000-1500. Is this possible? What do you all budget for a solo trip? It would probably be a four day trip
It's definitely possible. I got back in May 2013 from a solo trip that only cost 1,450.00.
I also flew down on Airtran since they had a great sale and used Magical Express and Disney's transportation only. I stayed at POR with a room only discount. I could have spent even less if I had stayed at Pop Century which I considered.
I ate at only a couple of TS restaurants, ate breakfast in the room with food I brought with me in my checked suitcase and added some fruit I bought in the food court.
Instead of a full lunch, on the days I had TS booked for dinner, I ate a couple of snacks for lunch like popcorn and a mickey bar to save money (yeah - that's my story and I'm sticking to it.

). Other days for lunch or dinner, I would order food without the extras like no fries since I get tired of those anyway.
I do have an AP though so I didn't have to buy tickets.
I spent 400.00 on souveniers which was more than the cost of a 4 day basic ticket so if you deduct the 400.00 from my above total, add in the 273.00 for the 4 day basic ticket right now, you are still under 1,500.00.
I hope you get to go - Disney World is fun solo.
