Hello team <3

My Wife and I are intending to travel SE Asia (predominantly Thailand) as follows - Arrive Bangkok 17th May 2024

10 Days Thailand (Bangkok & North)

25 days Laos, Vietnam & Cambodia

25 Days Thailand (Bangkok & South)

I realise that UK travellers have a 30 day Visa exemption for Thailand.

Is there any advice on what type of Visa we require for the second step of 25 days? Or do I need a METV or similar?

Also, seeing as the 30 day exemption period would have expired by the time we re-enter Thailand by 5 days are there risks when trying to fly from Sieam Reap into Bangkok at this point, will we be refused entry?

I believe that UK ordinary passport holders can travel to Thailand without visa for no longer than 30 days (maximum 2 times/year) so am I covered for the second visit as things stand as this would equate to 2 x 30 day periods?

I've been researching for 1-2 days now and have brain ache, discovering this group has given me some hope.
