Borders and Customs: B1/B2 One Month Single Entry Visa with Annotation

Hi,

I received my US Visa:
Entries: 1
Issue date: 29 Aug
Exp. date: 09 Oct
Annotation: University of Texas at Austin, Austin, TX


And i already have an invitation letter from the University of Austin for my training course from 03 OCT to 07 OCT at Texas
it`s my primary purpose and that`s what i told the consular officer at the embassy ...

But it`s my first time to USA and i would like to make some tourism one week before the course as:
Arrival JFK 24 Sept
NYC for 2 days
Arrival MCO 27 Sept
ORLANDO 4 days
Road trip from Orlando to Texas 02 OCT
Training course from 03 OCT to 07 OCT
Departure IAH (Houston) 08 OCT

Is this allowed with the given annotation?

Thanks!
Rami S.
