you must mean International Drive in Orlando. Orlando's the city with the most fun stuff to do. I think if you talk with your motel/hotel people, they can find all the transportation you will want. Do it ahead of time, tho. I presume you have already made reservations (?). The big hotels have their own transportation to the places like Disney World, Sea World, and Universal. I am sure they must go to other places too. There used to be Church Street Station, but I think they shut that down - if it's still there, go at night if you can. It's in the middle of downtown Orlando, but I believe my son told me they closed it - shame. It was wonderful and you could spend many hours there. There are many restaurants and night clubs (if you're not too tired at night) - every sort you will want - in Orlando, some restaurants have shows while you dine. If you have some specific questions, just let 'em fly this way and maybe we can solve it for you.
If you head for Tampa you will want to see Busch Gardens. It has an African theme. A lovely place to visit and spend a day - or two. Lots of rides and things to see (many animals). While in Tampa, you could take in Weeki Wachee Springs. It's just a hop/skip from Tampa. Has a famous underwater ballet.
If you go to St Augustine, you can drive yourself - not as much traffic. There is the famous and oldest fort in the U.S. in that city. aCTUALLY, it's the oldest city in U.S. Spaniards started it first. In OLD St Augustine there is the Fountain of Youth (just a simple hole in the ground, tho). The original homes are in a square and it's been restored to its original state - houses are adjacent to each other, joined actually. Lots of little shops, ice cream stores, cafes to visit. It won't take you a whole day there.
Anywhere else you might be going? We can fill you in.
I can't blame your husband for not wanting to drive in Orlando. I lived there for six months and the traffic was horrendous then - can't imagine what it is since nearly 20 yrs ago. I-4 (main highway through Orlando) was built without knowing what was going to happen in Florida and they made a huge miscalculation when they built it. It should be about 8 lanes on both sides but it isn't.
P.S. don't go to Miami - it's filled with crime. Tourists have died there. Be careful on International drive, too. It was and maybe still is where night people hang out (prostitutes, etc).
