Tanzania to Zanzibar trip

Our family just signed up for the Kenya/Tanzania safari departing 6/14/2014. We are extremely excited -- however, I was looking at the Tanzania to Zanzibar tour and saw that the accomodations include more tented camps, whereas on the Kenya tour, there is only one tented camp along with five star accomodations at the Four Seasons and other beautiful lodges. Just wanted to get some feedback as to whether we will be missing out on the "true safari experience" by not staying in more of the tented camps. We are real nature lovers and would love to have the thrill of hearing the lions roar at night and hearing all the night sounds of the animals. We can easily switch tours so that is not a problem. Would appreciate some guidance here.
