32 Pattaya / Chonburi Alternative Quarantine (AQ) Hotels

Pattaya / Chonburi Alternative Quarantine (AQ) is the list of government-approved quarantine hotels that can be used for the process of quarantine in Pattaya / Sriracha  / Chonburi. Pattaya /  Sriracha  / Chonburi AQ packages are offered for foreign tourists and other travelers arriving to Thailand.


Important Update! Starting from 1 November 2021, AQ hotels will be providing 1-night packages for vaccinated travelers arriving to Thailand from specific countries without having to undergo quarantine.

New 1-night packages1-night Entry Packages

New 7-day packages7-day Sandbox Packages

Unvaccinated travelers will need to undergo a 10-day quarantine at AQ hotels like previously.

Updated 10-day packages: 10-day Quarantine Packages


Booking AQ Package Hotels

To make reservation of AQ package, you can contact hotels directly. Part of quarantine hotels can now be booked online via Agoda but you must use special URL / links that separate quarantine packages from ordinary room offers that cannot be used when applying for COE. 

Pattaya quarantine hotels on Agoda can be accessed via this link: AQ hotels in Pattaya


Important note! In case of a positive COVID-19 test result you will be transferred to the hospital and will be responsible for all hospitalization costs. While most of COVID-19 insurance policies will cover your treatment if you will get sick with symptoms, your stay at the hospital in Thailand might be not covered if your case will be asymptomatic. Make sure to get an insurance policy that would cover asymptomatic cases. AXA's Sawasdee Thailand is one of the best options that cover medical expenses regardless of the showing of symptoms.


Recommended Quarantine Hotels


TIP! Some AQ hotels do not accept credit card payments, others charge extra or use unsafe payment authorization methods so paying a deposit or full prepayment to hotel’s bank account might be a better option even if you don’t have a Thai bank account. For making payments to Thailand we recommend ‘Wise, formerly TransferWise’ as it uses the mid-market exchange rate and charges just a fraction of that banks charge for international transfers. We use Wise for making our monthly payments from Europe to Thailand and it saves us a lot on transfers (e.g. for a transfer of 1000 EUR from Euro to Thai Baht we pay just 6.76 EUR commission, several times less than our European bank charges).


List of Pattaya Quarantine (AQ) Hotels

Currently, there are 32 hotels on the list of Pattaya / Chonburi Alternative Quarantine Hotels.

Note! Most Pattaya quarantine hotels are very slow presenting their 7-day and 10-day quarantine package via official channels so you might need to contact them directly for getting an offer while the list will be updated.
