Personally, I believe that "full time" means that you've tried for a substantial time to do every single thing that YOUR emotions allow for in attempt to feel like a woman. I do not believe that "full time" should mean strictly that someone dresses like a Leave It To Beaver housewife or uses the women's bathroom all the time, because in some communities, people do not react well to an extremely obvious looking MTF using a female bathroom, or using any bathroom at all; a safe alternative is using family bathrooms that are "single", and trying to adjust your life to a Trans lifestyle instead of having to do every single little thing as a woman would. The simple truth is that in our age, things are still unsafe for people who do not physically pass well; look at the McDonald's incident.
To me, other alternatives that IMO should work just as fine are dressing in the clothing items that matter to YOU (no matter if they are male, female, or in between, or are just pieces of clothing that are not special or defining to anyone but you), and expressing your personality exactly as you feel comfortable doing. I believe entirely that "full time" is a process that encorporates hormonal transitioning and/or facial surgery, hair and make-up transformations, confidence and adjustment building, and of coarse, the traditional "act like a woman" steps that the therapists recommend. However, in this age where women are largely no longer "stereotypical", I believe that acting like a stereotypical woman is truly the least important step in transitioning in a real world way. Simply put, people will look at your face and chest before they look at how you act, studies around the world prove it.
Intense behavior therapy should be only an option if surgery and/or hormones do not work for you, or if you seriously are lacking in the behavior department (and one must ask: if you don't know how to act like a woman naturally, how do you know that you are one?). To me, the only "behavior therapy" step that should be of any importance is voice therapy, as it is a physical change and not a "behavioral/clothing" one. I don't care how many crossdressers are out there that may just have a crossdressing fetish, clothing is the least important thing in my transitioning essence, there are literally BILLIONS of women who wear male clothing every day, wether because they have a masculine personality or they simply roll out of bed in pajamas. If I was transitioning just to wear a dress or a blouse, I'd think of myself as having a pretty sad excuse.
