Hi Op, before booking double check that you are not hitting Orlando on a long weekend.
I was there in Feb with by OH, we avoided the packages and went out on our own. It was a public holiday on the Friday so it was very very busy!
We live in the US so got cheap enough flights there.
Got our hotel at booking.com - there was a special offer on that weekend. The hotel was located on International Drive.
Most hotels will do shuttles out to Disneyland and Universal if you want to avoid hiring a car for a few days - you will be in these parks from morning to night so only us the car getting too and from the place.
We more than covered Disneyland in a day (different story if you have kids) - though if you go during a long weekend some rides will involve an hour of queuing - learn about Fastpass - it will be your friend when there are queues!
You need at least 2 days for Universal Studios
We hired a car to go out to the Kennedy Space Center - about 1.5 hours from our hotel and will take up a full day.
There were plenty of other parks and attractions to see.
