Okay - I used to crew on the City of Burbank ToR floats and used to work at a building on the corner of Lake and Colorado, so I can really help here.
1) Stay in either Glendale or in Pasadena, if you can still get a place. You can even do Burbank as a cheaper option. There is a Holiday Inn, a Marriott, a Courtyard, Extended Stay, a Best Western, and others located very close to, if not right on the freeways (5 or 134 - doesn't really matter at that locale).
2) The floats are actually lined up on Orange Grove Blvd in Pasadena and ready to go by Midnight. If your float isn't there by then, it doesn't qualify for judging and there are penalties (cash ones, too). This really rocks. You literally can walk through all of them at the stroke of midnight and just have a blast. The flowers are so incredibly fresh and you are feet away. Final judging is at 3am. Winners are announced at 6:30am.
3) If you have reserved parking, the lots are designated. We had bleacher seats by the Paseo one year and that was our lot. Very easy. You didn't indicate where you ended up for bleachers, so that will mean a lot as to when you get there. The closer you are to the corner (Orange Grove and Colorado) the earlier you need to be in place. You can go really early and then walk the floats before taking your seat if you are in those premium seats.
My best advice:
- I went at 5:30am on the years that I wasn't there with my float.
- I also packed a picnic breakfast with champagne and snacks. We were so decadent! You will need to have your own stash of snacks. It's a long time for the parade to get to some of the portions of the route!
- They actually open the streets for those camping out overnight at 12:30 noon on 12/31. Porta-potties won't be pleasant in some of those areas, either......
- Make sure to bring blankets to sit on. Those bleachers are mighty cold!!!!!
- Don't be shocked that when you drive around Pasadena after it's over, the city will look like a post-apocolyptic abandoned city. First time I saw it, that was my impression. Mounds of trash and debris...
This will be a truly great experience for you. Enjoy every minute of it!!!!!
