I spared the cash for an open return ticket train ticket, booked 1 night for a hotel in London & just live day to day for a little city break. (I am aware i will probably have to hotel switch if i'll be booking it night by night else it will look dodgy but that is fine)

I've had so many people asking if i'm coming to London since i changed my profile it's crazy. I'd like to give it a go down there given my niche. I cost up the price of an actual tour/city break but because i want to holiday there too it was a good ?2000 for a week of cramming fun & work in. So if i just made it up as i go along would that be suffice, i mean if all things go bad, i have the return ticket O:)?

TBH that is what i was doing when i first started, My first month out of a hotel saving for an apartment (i don't want to live down there mind you, just have a pricey city break is all). A bit DIY is all i'm worried about.

Opinions... i really want to do this but undecided?

It depends on just how far you're travelling, but open returns are the most expensive sort of ticket you can get in their class. It'd be cheaper to book an advance single for a day or two's time and keep enough for a coach journey back if you need it.

If you book different hotels from day to day, you have to move between them (duh) and that usually means leaving by say 10am and not being allowed into the next place several hours later = you've missed that day's lunchtime trade.

Very very few hotels are going to moan about you extending your stay by a day at a time, especially if you have paid for the next day before you'd have to check out.

Will it be worth it? No idea. What's the niche and how many of the people asking you to come to London are prepared to give you a deposit?
