Yes. It will be a crash course and may wipe out your vacation to some extent. You will also fly through some things you may find a vested interest in slowing down to actually lock down, but Yes, you can get your OW cert dives in and still get your AOW done.
I did my OW and AOW certs in 5 days total in the Philippines years ago.
You can do no more than 3 instructional dives in a day, so if you talk with the instructor and let them know your intent/plans, you COULD do 3 OW dives on Day 1, 4th OW dive and 2 AOW dives on Day 2 and then the last 3 on Day 3 and viola... it is amazingly fast, and it would behoove you to actually go at a slower pace then break-neck speed, but if you are there a week, you should be able to do it. If you are thinking of doing that, you may want to get the Adventures in Diving book now and start reading. You will HAVE to do the Deep and u/w Navigation dives... the other 3 will be at the discretion of the instructor/available conditions/discussions with the instructor. But if you have the Deep and Nav done, then it will allow you to enjoy at least a little more of your vacation.
Good luck and have fun!!!!!!!!!!
