If you are from the UK - then I agree with what Sammie said - get a car. It really is easier than you think.
Secondly if your BF wants to walk to a bar/restaurant on I-Drive every night then he will be dissappointed at VV because the trolley is ok now and again but not several times a day. VV is a long way down I-Drive, well past Seaworld.
Having said that VV is a good choice but you really need a car. You will be sick of waiting for buses etc from getting to/from Disney to want to do it all again at nite. Not much of a bar or restaurant on site at VV.
