Vegas Trip Cost?

Hi everyone, need some advice about going to Vegas to play in the WSOP next year.

I was planning on going in 2020 after I turned 21 but obviously COVID happened and scuppered those plans, and the past 2 years I have gone on family holidays instead but next year I am 100% planning on fulfilling my dream of playing in the WSOP.

I'm not planning of staying the whole series, just for 2 weeks (or 3 if I make it into the 2nd week of the Main) so looking at this year's schedule i'd have arrived say a week before the Main began (25th/26th June) and planned to leave on Day 4/5 of the Main unless I made it that far obv

Tournaments from this year's schedule I would've planned on playing:

26th June - 27th June: $600 deepstack
27th June - 29th June: $500 Salute to Warriors
28th June - 2nd July: $400 Collossus
1st July - 3rd July: $1,000 Tag Team (if I can find someone)
2nd July - 4th July: $1,000 Mini Main Event
3rd July - 4th July: $800 Independence Day Celebration NLH
3rd July - busted: $10,000 Main Event

And If I bust the Main early then maybe 1 or both of these:

$1,000 NLH
$600 Ultrastack

Obviously I might not be able to play all of these depends on how I get on etc but that's what my rough schedule would've looked like, total buyins of $15,900.

So I reckon i'd need roughly $16k for buyins, not sure how much for cash games what are the usual stakes played in Vegas? I'm used to playing £1/£2 at my local casino but let's say I bring an extra $4k for cash games so currently at $20k total.

But what about travel/accomodation/other costs etc? I'd be travelling from the UK and a rough search of flights.com says a round trip would cost about $1,200. No idea about accomodation though, any advice where the best places (BnB/hotels near the Strip) and the cost of these would be much appreciated.

What about travelling whilst in Vegas, is everything pretty much walkable or is it advisable to get a taxi/bus or even rent a car? Not sure if i've missed anything but any advice and help would be much appreciated. Thanks!

I'd say my total cost would be around $20,000-$25,000 or so, is that realistic? I know next year's schedule might be different but let's assume it'll be the same as this years to make it easier.

Thanks again!
