Due to a move early in the spring this year i found myself duddenly a lot further away fmo my old allotment.... previously it had been about mid-way between home and work, and as I drove every day it was always easy to visit it. Then I moved 30 miles away (closest I could afford to buy a house) and began commuting by bicycle and bus.... now that meant the allotment was a good 20 minutes away from work and I'd still need to cycle back (for 20 minutes) to get the bus home.
As you have some space in beds at home as well, I would suggest you adopt the plan that I used for the plot. Basically I divided it yup into four sections, one was for potatoes (maincrops), one for squashes and pumpkins, one for shelling beans and one for onions. For me these are all crops that you have a big day planting out (all bar the spuds were started in modules and small pots), have a biggish day harvesting (OK, the beans come in over a longer period) but between times don't demand too much in the way of attention, getting up there once or twice a week for a few hours weeding and watering was all they needed...
Don't feell that that is a planting recommendation, it's a strategy one, you might have other crops that fit the bill, but anything that needs a lot of attention, stupid amounts of water, picking over regularly or counts as a winter vegetable I'd keep at home, stuff that doesn't, grow on the plot....once you've had a year of this then it's easier to decide whether to keep it on and push forward with it....
