hi i00t2000. I don't know if this helps at all, but I will write about my past experience: I was offered a funded PhD position at one university, I liked the supervisor, resources etc but I wasn't sure if I liked the town. Then they sent me all the paper work. I didn't return anything back, because I was waiting to hear from the other university that I applied for a place. When I heard the positive reply from them, I considered the pros and cons and decided to go for the 2nd offer, and kindly turned down the 1st offer. But it didn't end there. I received a horrible (quite long) email from the supervisor from the 1st offer and he talked about how much I waisted their time etc. My current supervisor convinced me that it was a very unprofessional behaviour and every PhD candidate has to have a plan B etc. Now I am on my final year. I will never know how it would be if I chose the 1st offer, but that doesn't matter really, does it?
