A pretty quick work trip has been planned. I will fly into Heathrow Saturday morning. I'll have until Sunday evening to get to Warwick. I'll be in Warwick for 5 days before flying back out the next Saturday.

I'm looking for any general advice but also if there is anything specific to the following:

• I'm going to book my own hotel in London the Saturday night I fly in. Saturday and Sunday are essentially my "tourist" days. Where is good to stay? Not too concerned with price.
• I'm taking a train to Warwick and mostly have that figured out but is there an app or pass that I should add to my Apple wallet for transit around London?
• I like museums of all types. Are there any in particular I should check out?
• Any classic pubs or restaurants I should try to get to?
• Once the week starts I don't think I'll have much time to do touristy stuff and I won't have a car. Any recommendations on things around Warwick/Birmingham that I can get to some evenings via train or bus?

Looking for ideas - we're two adults in our mid-30's, no kids. We'll be leaving a wedding on a Monday in Ipswich but our flight home from London isn't until Friday. We'll be spending a week in London beforehand so we'd like to explore the countryside.

The only thing we've (sort of) landed on is seeing/staying in the Cotswolds, and touring some castles (holy crap there's a ton to chose from). We're not big drinkers/partiers but I'd like to be able to go hang out in a real English pub and stay at a Lord-of-the-Rings kind of inn (I already found the inn that the Prancing Pony is based on - thought not sure if we want to stay there).

Other random thoughts. Unfortunately our schedule doesn't seem like it'll line up with any Premier League games. Not planning on renting a car but can if we absolutely must. Would kind of like to stay in one spot since it's only 3 nights.

Hey y'all, I was wondering if anyone had any advice/warnings/comments/thoughts/etc. about an anniversary trip (10 years!) my partner and I are planning for late May. For context, I have been to the UK before a few years back but my partner has not. Also, I'm American and I've never driven anywhere but the US. This is the rough and very basic itinerary:

Day 0: Edinburgh

• Land in Edinburgh
• Check in to hotel
• Wander around the city

Day 1: Edinburgh

• Rent car
• Drive to St. Andrews
• Drive around in the Scottish Highlands

Day 2: Edinburgh > Redmire

• Drive south to a bed and breakfast in Redmire
• Check out the English countryside

Day 3: Redmire > Manchester

• Drive to Manchester
• Turn in car
• Check in to hotel

Day 4: Manchester > Bath

• Take a train to Bath
• Wander around Bath
• Stay at bed and breakfast

Day 5: Bath > London

• Take train to London
• Check in to hotel
• Do touristy things
• Eat a lot of food

Day 6: London

• Anniversary dinner

Day 7: London

• Wander around
• Eat a lot of food

Day 8: London

• Depart from Heathrow

I fully intend to add plan out the details and activities as we get closer, though I would be grateful for any recommendations for things to do or places to see. It's my partner's real first time out of the country and given it's an anniversary trip I wanted it to be mostly relaxed.

The first half or so of the trip is predicated on me, an American who drives on the right, driving good distances in the UK. I've plenty of experience doing long distance driving in the US, it's mostly the driving on the opposite side that concerns me. Is this recommended? Would it be better to just use rideshares or transit in the cities and take trains over the longer stretches between instead of a mini-roadtrip? Thanks y'all!

EDIT:
Thank you everyone for your thoughtful responses! I will try to get to as many as I can as soon as I can!

I am taking a trip soon to London and will possibly be adding a couple days in Paris. It's been a hot minute (few years) since visiting the UK and would like to solicit some timely advice and tips. One thing that comes to mind: How important is it to carry cash? Would I need to pay London and Paris street vendors or any shops with cash or will a card with no exchange fees suffice? While we will of course be visiting some tourist attractions like museums, most of our time will be taken up with book stores, record shops, food and coffee shops.

My wife and I (from the U.S.) are going on vacation and as part of a larger itinerary have scheduled a week in Northern Ireland, based in Belfast. We'll spend the first couple of days decompressing and exploring the city, but besides that I'm wondering what would be worth doing there during that time. I've been focusing on the other parts of our itinerary and have only very limited knowledge of that area and its attractions. We plan on renting a car for a day or two to get out of the city but otherwise will be relying on public transit. Thanks in advance for any recommendations or advice!

For the first time in my life, I'll be living somewhere other than my hometown— going half the world away to London!

Having never moved further than like an hour away from where I grew up, I'd love to hear about experiences, tips, things to keep in mind when moving to a totally new place. Anything centred on London/the UK is of course very welcome, but I'm also really into hearing from people more generally :)
