Last time we booked a hotel room we had a suite. There was a sofa bed for two kids and one in a cot. Worked well. Have you tried just ringing a hotel and seeing what they suggest and see if they could recommend somewhere.
No help at all here, but would also like to thank Fennel for that link. One f my children is having t stay with my parents when we g away this weekend as we just couldn't find anywhere to accommodate us all together.
Just wanted to join in briefly to say that in the future this will also be an issue for us!
I couldn't believe it when we looked at the Alton towers hotel to find that they don't allow more than 1 infant under 2 in 1 room! So if we wanted to say there (which we don't want to now...) we would need to pay for 2 rooms!
Complete rip off...are alot of hotels like this, so we are destined never to stay in a hotel for the next 18 months??
We have stayed in a few hotels with 5 of us in one room, they tend not to be the chains. The Big Sleep in Cardiff was nice, and allowed 5. We stayed in one in the north of Scotland too - Lochinver - but that's so far from everywhere that there's not much point recommending it to most people.
Being 5 does mean we never get those sorts of cheap deals other people seem to get with travelodge etc. But then I don't actually like travelodge so am not too bothered about that.
We stay a lot in youth hostels, rooms for 5 or 6, some of them have been refurbished and have en suite bathrooms and they are not massively cheap, similar to cheap hotels, but we find them very family friendly with 3 young children, lots of space to rampage around, and nothing much to break.
