Use the restroom before you leave the airport. Your bags will be fine. If 7 of you are taking the water taxi, you'll keep each other company. Go for it!
In truth, decide where you want to spend your money. I have taken the water taxi from San Pedro to Chetumal. No big deal. I happen to enjoy being on a boat and the scenery.
I have taken the ADO bus from Cancun to Belize City overnight. That extra few hundred dollars allowed us to choose to stay an extra night in San Pedro.
If you have spent the past 14 hours in transit, then it might feel better to spend the extra money and get to San Pedro 30 - 45 minutes earlier and feel less road weary.
Whatever you decide, you will love Ambergris Caye!
