Advice on big event coming up...?

I have a really big event coming up and I am not fat I just want to tone and maybe lose a little flub my thighs and tummy area...I am doing zumba and I love it..but the thing is that I have to do it everyday to keep in shape until June 20th to the 23rd...I will be wearing a dress and a bathing suit that is a bikini top and mini bathing suit shorts...any advice on how to keep sled motivated and how to look forward to coming home everyday and doing zumba...I have all of the zumba CDs...and I usually only do the 20 min or flat ab work out bc I am so short on time and it works amazingly when I do it straight everyday...but sometimes I do have enough energy to do it so I stop and don't do it and then I don't do it for days so I start to get flubby...thanks! 
