Saturday night we stayed in a B & B on Anglesey. Their wifi is so slow that speed test results are quoted in mb/sec! The owner is getting so pee'd off with this & the failure of four BT "engineers" to solve the problem that's bought a mobile hotspot which he lends to guests . . . getting a mobile signal on Anglesey is quite an achievement!
We've spent about 40 nights in hotels & B & Bs this year; the only problem we've had was with a Hilton group hotel, where the alleged free wifi in public areas just connected to a payment page demanding $10 for 24 hours' access! Free to HHonors members, but only if the room is booked direct with Hilton, which ours wasn't . . . & in any case, we don't really need yet another hotel loyalty card & our experience of Hilton hotels has been, to say the least, mixed.
