My first trip to the UK was for 6 weeks. I had 4 bags total:
1 enormous, barely-made-the-cutoff-for size bag, which weighed 62lbs. (overweight)
1 enormous, barely-made-the-cutoff-for size bag, which weighed 48lbs.
1 laptop case (large professional one that was crammed with other items)
1 totebag (acting as a handbag)
Nobody questioned the amount of items I had in relation to the time I was staying.
On a side note, I did not know you needed a pound coin to get a cart for your luggage (I hadn't flown in over 10 years). I ended up having to drag two bags several feet, then run back and drag the other two bags, and proceed this way, dragging two bags, then running back for the other two, through the baggage area to the arrivals section. I was so exhausted (from not sleeping for 2 days and the flight), that I ended up kicking the last two bags the final few feet. I thought my future DH was going to split a gut laughing. I'm sure if anyone was recording it, it made quite humorous viewing afterward.
