I'm so glad a few people have responded positively. I completely understand that an on site visit with unlimited EP would make for a fantastic trip but at times it comes across that those on a budget shouldn't even bother. Honestly, I'd rather wait a bit, perhaps even skip a few things (or save them for next time) than just give up and never go at all. I feel pretty confident with my research that we'll do everything we want in our 3 days next month but if we don't we'll have done more than we would have sitting at home!
OP, go, do what you can, make a list of must-dos and do the rest after those things are done. Have fun and know that those of us on a budget aren't wasting our time- we deserve our fun too!
