So, we have been lucky enough to stay at Vista Cay 5 times since 2009 and our last two visits we have used the same Condo.
Why, - it is on the top floor with a wonderful view of lake cay, SeaWorld and beyond. It has a large balcony and many glasses have been consumed there! With three large bedrooms and comfortable living space and two bathrooms it has suited our needs perfectly and easily as a family of four and you could cater for more easily.
Vista Cay is a secure gated community away from the 'buzz' of International Drive but close enough to pop and eat there. However, it is only a 10 minute drive from Universal Studio's and about 20 minutes from all Disney World parks, with a large Publix supermarket (a bit like Waitrose in the UK) a 2 minute walk away in a small shopping complex with takeaways too. It also has a pool, hot tub, outdoor bar, small shop and a games room; so for us the best of all worlds.
If you want to venture further afield to say Daytona or Kennedy Space Centre (or Center as they spell it in the US) then you are only looking at a 60 minute drive.
In the unlikely event you have any problems with your Condo, the best people to help you are Lin and Geoff from Your Vista Cay - they are great and always on call or on hand - we love them!
If we go back to Florida, we will stay there again - no doubt about that!
Enjoy if you choose to go.
