THANKS! for all your responses. I’ve got some more questions and I’ll list our rough itinerary, along with the cost of sites covered by the London Pass. It’s definitely a money saver imo.
Saturday: Arrive St. Pancras from Paris (no jet lag) via Eurostar around 12:00—13:00. Visit British Library, within spitting distance of our hotel. Maybe ride a bus or the Tube later.
Sunday: Changing of the Guard, Harrod’s, Natural History Museum, and Apsley House. At Apsley, initiate nine-day English Heritage Visitor's Pass (to be purchased before leaving USA) which allows "free" entry here, at Stonehenge, Darwin's Down House, and many other sites around England.
Monday: Day trip, train to Cambridge. THRILLED to walk and eat where Newton, Darwin, Hawking, Watson and Crick and other giants have walked and lived.
Tuesday—Thursday: Out near Stonehenge. One day with a private guide (ain’t no way I’m driving on the wrong side of the road! Someone would die. Crossing streets in London presents enough hazard for us.) and one day to explore on our own—still need to see if a convenient regional bus service exists near us in Rowde/Devises. If yes, maybe see one or more of: Bath, Avebury, Salisbury, Caen Locks, Wadworth Brewery… Heck, the Locks and Wadworth seem within walking distance.
Friday: Arrive at Paddington around noon, stay near St. Pancras again. Visit British Museum (open late).
Saturday: Activate London Pass. Visit the Shard (£32), Borough Market, maybe Golden Hinde (£5), HMS Belfast (£18), Shakespeare’s Globe (£17).
Sunday: HoHo bus (£34), Darwin's Down House. Hope for light traffic for the HoHo ride on a Sunday morning…
Monday: Westminster Abbey (£22), Churchill War Rooms (£22)
Tuesday: HoHo boat to Greenwich (£19), Museum and Cutty Sark (£31), Greenwich Market, maybe more HoHo boat
Wednesday: Tower of London (£27), London Eye
Thursday: Short day to mosey somewhere, have 16:30 departure from Heathrow to USA.
Total admission costs if purchased on site easily tops £200 and could be near £250. Six day London Pass on sale is £135 and MAYBE we can skip some lines. I don’t think I’ve packed too much into any one day and I’m hoping our early April visit will mean relatively short lines anyway.
1) It seems to me that buying individual site tickets in advance for discounts is a logistical nightmare, what with probable timed or at least day specific entry. “C’mon, Honey. We can’t finish breakfast or we’ll miss our spot at Museum X.
2) April is likely gonna be rainy, right?
3) Based on responses so far, I see no need to purchase the Pass now. Is the current sale “typical” price-wise or might there even be better sales at times?
4) Will the GBP weaken or grow stronger vs the USD by April 2020? LOL
Nigel: based on responses and a (very) little digging on my part, it appears electronic connectivity and expending data time are not issues. I think all the device needs to do is show a bar code to be scanned. Just need to be sure the battery is charged.
