4 day pass or 5 day pass?

[Ellay]

Hi,

My holiday is getting closer now and I'm thinking of buying some passes whilst the exchange rate is still good. Problem is I'm not sure whether to get a 4 day or 5 day pass for WDW: Here's my plan so far:

4 nights at Radisson near Universal: thought I'd get just a 2 day pass for US, and maybe leave a bit of time for shopping?

4 nights on the Wonder;

6 nights at ASMo; I think most of our first day will be spent travelling / settling in, and maybe visit DTD in the evening. Will a 4 day+ pass be enough, or should I get a 5 day+?

Your valued opinions would much appreciated.

Thanks
