Hi @Sheila353 , I'm also a host in an English holiday area - Lake District coast. I joined in Feb 17, and in all 3 summers of hosting, August has been peak month, followed by July. Next most popular are June & Sept. My earnings bar chart is pretty much the classic 'bell formation' peaking in summer, tailing off in autumn, very little in winter, then building in spring - as you would expect.
I find I have bookings from tourists from March - Oct/Nov. People book for work all year round, some Mon - Fri, whilst doing contract work locally, or people who've started a new job & are looking for a flat/house. There's also salesmen & others just wanting 1 or 2 nights for work. I seem to host a lot of locum health workers/social workers.
Most of my bookings are short notice. I find workers book 1 day - 1 week before their stay. Tourists too will book for the weekend only 1 day - 1 week beforehand. In summer, many folk on driving tours book at breakfast the same day, sometimes the night before - & some only book 2-4 hours before arrival!
I didn't check your minimum stay....I find the most common length of stay at mine is 1 night! Followed by 2 nights! Very few tourists stay more than 3 nights; I've had 3 x 5 night stays & 1 x 4 night stay all summer. (Tho' mine is budget private rooms in MY house, shared bath/WC, which lends itself to shorter, rather than longer stays.)
I've had a steady drip feed of guests over the last 2 &1/2 years. Just when my calendar appears empty - up pops another one! - If you scroll thru my reviews, you'll see the monthly traffic, dropping to just 1 or 2 in Dec, Jan, Feb.
One thing, I often look at other listings in my area, & it strikes me that many round here are not getting many new reviews, even now in peak season......... Could be cos many new listings, thinly spread, or are guests booking on other platforms?
Good luck!
