Hi Julia M,
Yes, you can have specific PS reservations built into the plan. The software will schedule around them nicely. For meals for which you don't have PS, we'll be happy to make restaurant recommendations, too.
Two weeks is a good lead time to order. And we can do multiple requests for the same attraction, too. Buzz is fairly popular in that department.
The touring plans in the Unofficial Guide are geared towards summer crowds, so they should work well in August. Custom touring plans are generally most useful if at least one of the following is true:
1) Your group will not be arriving at the park when it opens.
2) You have PS reservations during the first few hours the park is open (especially between 9-11 a.m. in the Magic Kingdom), or at unusual times (e.g., dinner at 3:30 p.m.).
3) You want to see a set of attractions significantly different from those listed in the Unofficial Guide's touring plans.
So, if you're willing to get up early, eat at the usual times, and see the most popular attractions, you probably don't need customized touring plans; The touring plans in the Unofficial Guide will work great.
Feel free to send me an e-mail with more specific information. If the best fit for your situation is a simple tweak of the standard touring plans, we'll help out with that for free.
Thanks for writing!
