I've been to a few Anime conventions, and I intend to go to two more soon. Anyway, there are several things I've noticed about conventions, including the lack of sleep at a decent hour. When you do finally get to sleep, I figured I'd let you know where I've seen it happen, so that you may find a place as well. These are my top ten;
1. Hotel Bed (WARNING*; you may have to share with more than one person.)
1. Hotel Bed (WARNING*; you may have to share with more than one person.)
2. Hotel room Couch (WARNING; may not have much leg room.)
3. Hotel room Chair (They're very good for sleeping on your own)
4. Hotel room floor (WARNING; sleeping on floor, unless under a table [see no. 8] may cause rude awakening by being tripped over.)
5. Hotel room Closet (WARNING; Not for the clausterphobic)
6. Hotel room Bathtub (WARNING; sleeping in bathtub may cause unexpected awakenings in the middle of the night, possibly by having water rushing into your sleeping space.)
7. Under a bench. (WARNING; people may stop and stare, and possibly sit and watch you.)
8. Under a table. (See no. 7's warning)
9. Against a wall. (WARNING; security may ask you to go to your own room/hotel.)
10. In the Anime Screening room. (WARNING; Loud explosions may awaken you.)
Hope this helped! ^-^
