瑞士采购需求：豪华露营

I'm looking to set up a glamping site in Hungary and I'm really interested in your airtight inflatable bubble tents. Could you recommend the ideal size for a guest room that includes a bed and a small seating area? Also, instead of a soft tunnel, I'd prefer a steel-frame capsule tunnel for the entrance, if it's feasible. Please provide your unit price along with shipping costs to Hungary, including the nearest port and estimated delivery time post-order confirmation. Since these tents will be used for paid accommodations, I'd like to know about the material thickness, any fire-retardant certifications, and relevant CE or EU safety documentation. Additionally, please confirm the warranty duration and coverage, along with your payment terms and minimum order requirements. Looking forward to your response!
