BD every day...?!

I know I know so many people have asked this question. I am just on vacation almost this whole month so my husband and I actually CAN have sex every day...I'm trying not to mention that I'm ovulating (starting tomorrow) so we can keep it carefree or at least for him. Is it BAD to have sex every day? Does he really need a full day in between to get fresh sperm? What has been your experience?
