I cannot PM you for some reason, so here are your andwers:
- EY has 787 sim and you will probably do your assessment on it
- I recommend taking the housing allowance over company accomodation, but you will be out of pocket probably considering you have wife and kids
- discounted tickets after 3 or 6 months in company I can't remember
- discounted tickets for life? never read anything official but have heard something about 10 years....but I think by 5 you will want to pull the pin anyway
Good luck
