My kids love Hop Inn because they all look the same, so they feel familiar. They're all on the very basic side, but quite modern and clean. In a place like Rayong there would be other inexpensive hotel options (in the range of 600 baht per night, but booking sites discount even that) but Hop Inns are cost-effective for covering the basics. There is a coffee machine that provides free coffee in the morning (and cocoa; that works for my kids), and a microwave, and they sell some snacks and CP frozen foods, and that's about it. The rooms have a refrigerator, free wifi, and nice, functional bathrooms. It's not a great option if you wanted to spend a lot of time in the hotel, and really for a beach outing theme you could be closer to the beach, but it works for us.
