1. The entire time you're in a queue, have an imaginary conversation with someone who isn't there. You'll see the other families whispering and giggling and it will just make the lines go a lot faster for all involved.
2. If you hear someone moving around your room, bear in mind that it is not your travel mate and your room is likely haunted. Sprinkle holy water (or your religious device of choice) and alert the front desk immediately. Unless you're really sleepy - then just tell them in the morning.
3. At table service restaurants make a ressie for two and order for two. Tell the waiter that you're going to propose to your sig other as soon as he/she shows up. After 30 minutes, put your head on the table and start crying while mumbling, "She went home! She went home!" They'll comp both meals.
4. Get a t-shirt that reads, "I'm with AWESOME" with an arrow point up, to you.
5. Disney's Best Kept Secret™ is Solo Swap. Details at this time are still coming out, but you do something like approach the CM at the ride entrance and say, "Never tell me the odds." If the CM says, "I'd just as soon kiss a Wookiee," Solo Swap is in effect! Simply proceed to the north side of that park's icon and stand on one leg until further instructions come. If the CM looks at you blankly, Solo Swap is NOT in effect and just slink away, laughing nervously.
6. With any snack item that comes in multiples (say, the three beignets at POFQ), don't be a pig about it. Only eat two and toss the other one high in the sky while screaming, "Free beignet!!"
7. My Magic Plus does not work for solo travelers. They will have a legacy fast pass machine at each ride for you (Everest not included, though no one is sure why)
8. Consider a discounted My Park Buddy - formerly sold by the now defunct SkyMall and, as they say, priced to move - MPB is a lightweight mannequin that attaches to you at the waist, allowing you free range of motion in both hands as your buddy (Jack...Jack is the only model left) makes his way around the park with you. While perhaps introducing some awkward conversation - "What on earth...." and "Is that guy allowed to be in here?" - it allows you to avoid any awkward conversations about why you're traveling alone.
