2 weeks to finish building muscle....

I was woken up with extremely sore muscles last night... (and a headache) I had to take pain killers as it was so painful (not into taking meds unless absolutely necessary).   

I have 3 weeks until my daughter wedding where I'm wearing a strapless dress and are trying to get to the best I can for this event (of lifetime photos) lol 

Currently, I have the next 2 weeks off before the big day. Then it will be full on I won't be able to have time for workouts which I thought would be good rest and building time.  So I thought, work really hard 2+ hours a day for the next 2 weeks with maybe rest days on the weekend if I have to then rest the week before the wedding...

I have been working on getting fit and healthy since February and the last 2 days have really stepped it up from 1 hour to 2 1/4 hours with cardio and weights. I would like to look like my profile picture, I'm about 5 kgs away from it...

My question is:- 

Do I push through the pain work hard and push myself as I wanted to or 
rest up and when not so sore hit it again or
Go back to 1 hour sessions

Thanks in advance for your advise and support
