Thanks for all the help on this thread.

I'm sure there will be more choices / suppliers etc. at better prices (possibly), but with only 54 days to go I needed to get these tickets now.

We have been to Florida many times, but never in Spring, so that's something new for us; also gives us the opportunity to get better value from the tickets by visiting Universal more than once for Mardi Gras (Smokey Robinson and Franki Valli are on when we're there)
