Limited number of writes is relative. Say, if you have an SSD with 100,000 write cycles and no wear-leveling, this means that if you hibernate 10 times a day, this drive will serve you over 27 years before the hibernation will wear it out.
However, most modern drives use wear-leveling, which means data is dynamically moved around so the cells wear out equally. See the specs of your SSD disk and judge for yourself if the hibernation ok or not. For example, Western Digital's consumer SSD drives are spec'd as follows (PDF):
Service Life 3 years
Maximum GB written per day: 17.5 GB (64 GB drive) 35 GB (128 GB drive) 70 GB (256 GB drive)
So, if your total RAM is 8GB, and actively used RAM is 5GB (rest is used as cache etc.), that 5GB is written each time you hibernate. Judge for yourself if that affects your drive in a significant way or not, based on its specs.
