I think you should do the deluxe. Since your alone, you can stay up late and space out your meals really well.
Since its not your first trip, I'm assuming you have visited the parks before and you probably won't feel like you missed too much by stopping at TS a few times a day. In my opinion, the Deluxe takes a bit more time away from the parks than the regular DP.
Will you have a car? or are you relying on Disney transportation? If you have a car, it is a big plus as you can drive directly to other resorts. If your using Disney, then you will have to transfer to other resorts which will also take some time.
If you are a picky eater or don't each much, you may want to consider the regular DP as the deluxe comes with tons and tons of food. If you think you'll throw most of it out and not eat it, you'll have wasted your money.
In my opinion, the deluxe is great because you can try all of the restaurants you want and experience so many new foods and places so I think you should go for it!
