According to this wiki
https://en.wikipedia.org/wiki/List_of_Falcon_9_and_Falcon_Heavy_launches
it says...
First launch of an enhanced Falcon 9 v1.1 launch vehicle, with a 30 percent increase power.[84] Orbcomm had originally agreed to be the third flight of the enhanced-thrust rocket,[87] but the change to the maiden flight position was announced in October 2015.[84] SpaceX have applied to the FAA to be able to attempt to land the booster on solid ground at Cape Canaveral.[91]
(As a side note it looks at the moment that the Falcon Heavy will launch in May 2016. More here about it. http://www.spacex.com/falcon-heavy)

Great details - we might pop over to see the launch - thanks!
Would you know if PLAYALINDA BEACH will be open for this launch. I have tried all numbers and unfortunately none answer. Also their hours are 6 to 6. Do they let you stay late for launches if they are open?
